1.	If the radius of the earth shrinks by `0.2%` without any change in its mass, the escape velocity from the surface of the earthA. increases by `0.2 %`B. decreases by `0.2 %`C. increases by `0.1 %`D. increases by `0.4%`
Answer» Correct Answer - C `v_(e)=sqrt((2GM)/R)` `rArr v_(e)prop1/(sqrt(R))rArr (Deltav_(e))/(v_(e))xx100=-1/2((DeltaR)/Rxx100)`

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).
