1.	The escape velocity of a body from the earth is `V_(e)` if the radius of earth contracts to `1//4` th of its value keeping the mass of the earth constant the escape velocity will beA. doubledB. halvedC. tripledD. unaltered
Answer» Correct Answer - A Escape velocity `V_(e)=sqrt(2GM)/(R ),R=(R )/(4)` opr `V_(e )=2 sqrt(2GM)/(R )` since G and M are constant hence `V_(e )=2v_(e )`

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).
