A body projected vertically from the earth reaches a height to earth's

1.	A body projected vertically from the earth reaches a height to earth's radius before returning to the earth . The power exterted bythe gravitational force is greatest ………..
Answer» at maximumheight of BODY at the instant just before the body hits the earth remains CONSTANT throughout motion at the instant just after the body is projected SOLUTION :When the body is projected ,its VELOCITY is opposite to the gravitational force HENCE work done on gravitational force and it hit the earth ,its velocity is maximumand it is in the direction of gravitational force . So power is gain by gravitational force .
