1.

Within a few pages the author has packed the important events in the lives of John Ipe and his wife. Discuss how conciseness and economy of expression can achieve effective portrayal of entire lives.

Answer»

There are two ways of narrating a story, one style is the elongated narration with the detailing of each and every emotion and situation giving length to the story. The other style is crisp one that keeps the story short yet highlighting the important events and emotions. Roy has narrated using the second style. She has kept the story short, yet she did not miss out anything. She has described the relation of a husband and a wife with all the necessary details, though she did not ponder over the sentiments for long. She explained the face of the society we live in. Jean Genet was so correct when he said that society dwells on images and this is what Roy has tried to emphasise in her story. John having lost the chance to gain the recognition, he could have, felt the loss of identity along with it. Roy is economical when she describes the emotions and makes sure that nothing worthless is portrayed. All that she has spent in the short tale is worth the while. The narration is simple enough and achieves effectively the portrayal of the entire lives of the characters. The disturbance in the marriage, the physical violence, the emotional loss, the intervention of the young child and its impact on the father. All have been portrayed wisely not wasting any time or making the reader to wait for the following happenings.

2.

How does the author succeed in raising crucial social issues not through open criticism but through subtle suggestion?

Answer»

Roy hit the nail right on the head in describing the male chauvinistic society we live in, though suggestively. How pride is all that matters to a male and for a female, no matter how cruel her husband is and even if the love is worn out of their relationship, her want for him never ceases. This the society we live in where a male beats her wife no matter how qualified he is. It does not matter if he is a top notch government official who comes from a so called modern background, he can not tolerate his wife's success. A man always wants his wife to be a subordinate to him. It is in our minds that a woman can not rise higher to her husband. It is also highlighted in the story that how we run after momentary pleasures. Recognition is important for a human undoubtedly; however, the way Pappachi ruined all his life and relations because of what he did not get, rather than accepting that may be it was not fated after all. We humans, especially men, crave for fame and recognition. In what of what we can not have, we lose what we have.

3.

Approval from the outside world and approval within the family.

Answer»

Mammachi was a woman with exceptional talent and of this Pappachi was jealous. Once when her violin teacher remarked on her being so talented, Pappachi called off the classes. Even when later in life when Pappachi was retired, his ego did not give way to soberness and he disapproved of her flourishing pickle factory. The Kottayam Bible Society in Ayemenem was full of appreciation for Mammachi, while her own husband looked down upon her. He was jealous of his wife's success, a male chauvinist, Pappachi was not an ideal husband in any case who had a dutiful wife he never appreciated.

4.

Why does John Ipe consider retirement to be a dishonour?

Answer»

Benaan John Ipe, Pappachi, got retired from the post of Joint Director, Entomology. He was a reputed man. He was proud of being a high-ranking government officer; however, now retired he was finding it difficult to cope with the ignominy of retirement. He was seventeen year older than Mammachi and realised with a shock that he was an old man when his wife was still in her prime. He had always been a jealous man and he resented the attention his wife was suddenly getting. For him his retirement that was a constant reminder of his old age stung him deeply. A man who was once so strong to beat down his wife with brass vases was not put to a stop by his young son. He felt neglected and dejected. A once Imperial Entomologist was now reduced to a withered old man and this gave a jolt to his ego.

5.

How does Mammachi stand out as an independent resilient woman in the text?

Answer»

Mammachi was a woman who was always discouraged by her egoistic Entomologist husband. He never supported her and was jealous of her talent and any sort of attention she received. Probably it was so because of the frustration pent up inside his heart for not receiving the deserved fame of his discovery of the moth he wished to be named after him. However, her pickle recipe was a famous one and she was called by the Kottayam Bible Society to make some of her famous banana jam and tender mango pickle for an upcoming fair. It sold quickly and received more orders than she could cope with. Thrilled with her success, Mammachi decided to persist with the pickles and jam and was kept busy for the whole year. Gradually she set up a pickle factory and made a success of it.

6.

Comment on the relationship shared by Mammachi and Pappachi.

Answer»

Pappachi and Mammachi had a gap of 17 years. A retired high ranked officer, Pappachi was always jealous of Mammach's talent and of the attention she received. Whether it was pickle making or her violin classes in Vienna, Pappachi was always jealous of her. Despite of all the friction they had in their relationship, Mammachi bore with him. Mammachi was more used to Pappachi and was not exactly in love with him. Pappachi used to beat him with brass vases and still Mammachi could not let go of him. She wept bitterly on his funeral not because the man she had loved was gone but because he will not be around her any more. He was an old shoe for her and she could not let go of him. She was too attached to him, to having his slouching around the pickle factory, and of course, used to being beaten by him.

7.

Chako's firmness in dealing with the irrational behaviour of his father

Answer»

Pappachi used to beat Mammachi with brass vases every other night until Chako came home for a summer vacation from Oxford. He had grown into a big and strong man. It had been a week to him since he arrived that he found Pappachi beating Mammachi in the study. Chacko strode into the room, caught Pappachi's hand by which he held vase and was beating Mammachi and twisted it around his back. He told loud and clear to Pappachi that he would not want the incident to happen again, ever! The father was flabbergasted. He never dared to touch Mammachi again and yet he never talked to her again till he lived. The firm attitude of the young son stopped the domestic violence that used to take place every day in the house. It was a good action taken by the boy. Men in our society beat their wives without any cause just to prove their physical superiority. The boy made it clear to the father that he is not the only one with muscles in the house putting a stop to the violence.

8.

11.

Name the factor on which coefficient of friction depends?

Answer»

Coefficient of friction µs = F/R depends on the nature of surfaces in contact and nature of motion.

12.

Is earth an inertial frame of reference?

Answer»

No. earth can not be considered as an inertial frame of reference, because the earth is rotating and revolving, which means it is accelerating.

13.

A cube slides down a rough inclined plane of inclination θ with constant velocity. If this cube is projected up the plane with a velocity, v0 then at what distance along the inclined plane, the cube will come to roll?

Answer»

Since the cube moves down the plane, then the force of friction equals the component of weight parallel to the inclined plane.

i.e., f = mg sinθ

When the block is moved up the inclined plane, then retarding force

= mg sinθ + f = mg sinθ + mg sinθ

= 2 mg sinθ

Hence, a = {-2 mg sinθ}/{m} = -2 g sinθ

Now, μ = v0, v = 0; a = -2g sinθ, s = ?

Using v2 - u2 = 2as

⇒ (0)2 - (v0)2 = 2(-2 g sinθ) s

or, s = {v02}/{4 g sinθ}

14.

What is rolling friction? How does it arise?

Answer»

1. Friction between two bodies in contact when one body is rolling over the other, is called rolling friction. 

2. Rolling friction arises as the point of contact of the body with the surface keep changing continuously.

15.

Is the large brake on a bicycle wheel more effective than a small one? Explain.

Answer»

No, the large brake on a bicycle wheel is not more effective than a small one because the force of friction is independent of the surface area of contact. However, chances of brake decreases when area of contact is larger. That is why large breaks are preferred.

16.

Explain how lubricants help in reducing friction?

Answer»

1. The friction between lubricant to surface is much less than the friction between two same surfaces. Hence using lubricants reduces the friction between the two surfaces. 

2. When lubricant is applied to machine parts, it fills the depression present on the surface in contact. Thus, less friction is occurred between machine parts. 

3. Application of lubricants also reduces wear and tear of machine parts which in turn reduces friction. 

4. Advantage: Reduction in function reduces dissipation of energy in machines due to which efficiency of machines increases.

17.

Derive an expression for recoil velocity of gun.

Answer»

Let mg be mass of gun,

\(\vec v_g\) = recoil velocity of gun,

mb be mass of Bullet \(\vec v_b\)

Initial momentum = 0,

Final momentum = mg \(\vec v_g\) + mb \(\vec v_b\)

By law of conservation of momentum

0 = mg \(\vec v_g\) + mb \(\vec v_b\)

⇒ \(\vec v_b\) = - \((\frac {m_b \vec v_b}{\vec m_g})\).

18.

A bubble generator is kept at the bottom of an aquarium which is on a free fall. Will the bubbles generated rise to the top?

Answer»

No, the bubbles generated at the bottom will not rise to the surface, ‘this is because the water in the aquarium is in a state of weightlessness and does not give the bubbles a reactional upward force.

19.

A truck weighing 1000 kg is moving with velocity of 50 km/h on smooth horizontal roads. A mass of 250 kg is dropped into it. The velocity with which it moves now is –(a) 12.5 km/h (b) 20 km/h (c) 40 km/h (d) 50 km/h

Answer»

(c) 40 km/h 

According to law of conservation of linear momentum

m2 v2 = (m1 + m2 )v2

v\(\frac{m_1v_1}{m_1 + m_2}\) = \(\frac{1000 \times 50}{1250}\) = 40 km/h

20.

Ball-bearings are used in machinery. Why?

Answer»

Since rolling friction is much less than the sliding friction. so we convert the sliding friction into rolling friction. This is done by using ball-bearing arrangement. Ball-bearing are placed in between axle and hub of the wheel. The ball-bearing, tend to roll round the axle as the wheel turns and as such the frictional force is diminished.

21.

How does lubricants help in reducing friction?

Answer»

22.

The origin of friction is – (a) electrostatic interaction (b) electromagnetic interaction magnetic(c) photon interaction (d) interaction

Answer»

(b) electromagnetic interaction

23.

Mention a factor on which coefficient of friction depends.

Answer»
