1.	A body of mass m is projected vertically upwards with velocity v from earth.s surface and attains height ..h... Then (v_(e) is escape velocity )
Answer» If `V = v_(e )` then `h = OO` Ifis very small then`h = (v^(2))/(2G)` If h = R, then kinetic energy with which it is projected is mgR/2 If h = R then total energy is negative ANSWER :A::B::C::D
