1.	It was raining heavily one day. Prateek made a paper boat and started playing with it in a water pool at road side. He then got his toys and dolls and made them boat riders the boat sank in water. Prateek did not lose courage. He made another boat and used lighter toys as passengers and this time boat did not sink in water. (a) Why did not sink when loaded with dolls and toys? (b) Which force is exerted by water on objects immersed in it? (c) What qualities are shown by Prateek?
Answer» (a) The boat did not sink when Prateek used lighter dolls as the density of the dolls and the boat is much less than the density of water. (b) Buoyant Force is exerted by water on the objects immersed in it. The gravitational pull exerted on them is much more than the buoyant force therefore they sank. (c) Prateek is very patient as well as determined to achieve his goals. He does not lose hope and keeps on trying to fulfil what he wants.

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).
