Describe independent India’s achievements in science and technology and space research. |
|
Answer» India’s achievements in science and technology and space research after independence are very remarkable. Science and Technology: Progress of scientific research is a precondition of agricultural and industrial development. Technology and technocrats played a significant role in the development in India’s agricultural progress and industrialisation. Under Jawaharlal Nehru who was an ardent admirer of modem science and technology India attained great progress in science and technology. Several research institutes like Council of Scientific and Industrial Research, Indian Council for Agricultural Research, Indian Council of Medical Research, etc. came into being. Two stalwarts of Indian science Homi.J.Bhabha and S.N.Bhatnagar helmed the projects of Council of Scientific and Industrial Research. The Atomic Energy Commission was started in 1948 to utilize atomic energy for development. Eminent atomic scientist Homi.J.Bhabha was appointed as the Chairman of the Commission . He was also the head of Tata Institute of Fundamental Research. Several world class engineering institutes were started. Between 1954 and 1964, five IITs were started. Nehru’s strongly believed to minimize Indian’s dependence on western countries in science and technology. Subsequently India attained tremendous progress in medical science, biomedical engineering, genetics, biotechnology, health science, transportation, marine technology, information technology and atomic energy. Space research: Independent, India conducted various space explorations and experiments. In 1962, Nehru, with the technical advice of Vikram Sarabhai, formed the Indian National Committee for Space Research (INCOSPAR). Following this, in 1969, Indian Space Research Organization (ISRO) was established to lead space research. The first rocket launching station was established at Thumba, near Trivandrum. As a result of the collective efforts of India’s space research experts, first artificial satellite Aryabhatta was successfully launched in 4 975. In addition to satellites, space vehicles and rocket launchers were also developed. It was because of the farsightedness of Nehru that India became the first developing nation to make and launch satellites. The agencies that develop satellites in India include:
India has also advanced much in missile technology. Agni and Prithvi are the missiles developed by India. Dr. Raja Ramanna and Dr. A.P.J. Abdul Kalam led experiments in atomic energy sector With the new space missions Chandrayan and Mangalayan, India has entered a new era in space exploration. Chandrayan which began in 2008 is Indian’s first lunar mission. With this ‘ India became a member in the coveted group to launch space shuttle to the lunar orbit after USA, Russia, European Space Agency, China and Japan. Mangalayan is the space mission of India to Mars. It is the Indian made space shuttle that covered the long distance in space. India is all set to take new experiments in space. |

How did the achievements in scientific field help India’s development? |
|
Answer» Independent India achieved remarkable progress on science and technology fields. Science and technology has very significant role in India’s agricultural as well as industrial developments. Several research institutions and five Indian Institution of technologies were set up in India soon after independence. India also gained rapid progress in medical education, biomedical engineering, nuclear science, biotechnology, health, transportation, oceanic research information technology, space research, etc. All these developments lead to overall development of the country. |

The process of attainment of India’s freedom completed in 1961. How much is the statement valid? |
|
Answer» In 1947 Britain gave freedom to India. But regions like Goa, Daman and Diu were under Portuguese control while Pondicherry, Mahe, Yaman, and Karaikal were under French domination. In 1954 the French settlements were liberated while the Portuguese settlements were liberated in 1961. That is why it is said that India got complete independence in 1961. |

Consider two identical charges placed a distance `2 d` apart on the `x`-axis.The equilibrium of a positive test charge placed at the point `O` midway between them may be (i) neutral (ii) stable for displacement along the `x`-axis (iii) stable for displacement along the `y`-axis (iv) unstable for displacement along the `x`-axisA. stable for displacements along the x-axisB. neutralC. unstable for displacement along the y-axis.D. stable for displacements along the y-axis |
|
Answer» Correct Answer - A::C a.,c. If positive test charge is displaced along `x-`exis, then net force will always act in a direction opposite to that of displacement and the test charge will always come back to its original position. But if test charge is displaced along `y-` exis, if will never come back to its original position and will fly away along `y-`axis. |

Two very large parallel disks of charge have their centers on the x-axis and their planes perpendicular to the x-axis. The disk that intersects x = -R has uniform positive surface charge density `+sigma`, the disk that intersects `x = +R` has uniform negative surface charge density `-sigma`. (i) , Which graph best represents the plot of the x-component of the electric field vector on the x-axis?A. (i)B. (ii)C. (iii)D. (iv) |

Two point charges `q_1=q_2=2muC` are fixed at `x_1=+3 m` and `x_2=-3m` as shown in figure. A third particle of mass 1 g and charge `q_3=-4muC` are released from rest at `y=4.0m`.Find the speed of the particle as it reaches the origin. |
|
Answer» Here the charge `q_(3)` is attracted toward `q_(1)` and `q_(2)` both so the net force on `q_(3)` is toward the origin As only force acting is conservative we can use conservation of mechanical energy let v be the speed of particle at origin. From energy of conservation principle we get `Ui+Ki=U+K` or `(1)/(4piepsilon_(0))[(q_(3)q_(2))/((r_(32))_(i))+(q_(3)q_(1))/((r_(32))_(i))+(q_(2)q_(1))/((r_(21))_(i))]+0` `=(1)/(4piepsilon_(0))[(q_(3)q_(2))/((r_(32))_(f))+(q_(3)q_(1))/((r_(31))_(f))+(q_(2)q_(1))/((r_(21))_(f))]+(1)/(2)mv^(2)` Here `(r_(21))_(i)=(r_(21))_(f)` substituting the proper values `9xx10^(9)[((-4)(2))/(5)+((-4)(2))/(3)]xx10^(-12)+(1)/(2)xx10^(-12)+(1)/(2)xx10^(-3)v^(2)` or `(9xx10^(-3))((-16)/(5))=(xx10^(-3))((-16)/(3))+(1)/(2)xx10^(-3)v^(2)` or `9xx10^(-3)(16)((2)/(15))=(1)/(2)xx10^(-3)v^(2)` or `v=6.2=6ms^(-1)` |
