1.	A beaker full of water is suspended from a spring balance. Will the reading of the balance change : (a) if a cork is placed in water ? (b) if a piece of heavy metal is placed in it ? Give reasons for your answer.
Answer» The reading of spring balance will not change if a cork is placed in water because cork, being lighter than water, floats in water. (b)The reading of spring balance will change if a piece of heavy metal is placed in water because heavy metal being denser than water, sinks in water.

A beaker full of water is suspended from a spring balance. Will the reading of the balance change : (a) if a cork is placed in water ? (b) if a piece of heavy metal is placed in it ? Give reasons for your answer.

Answer»

The reading of spring balance will not change if a cork is placed in water because cork, being lighter than water, floats in water.

(b)The reading of spring balance will change if a piece of heavy metal is placed in water because heavy metal being denser than water, sinks in water.

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
