1.	A body projected vertically from the earth reaches a height equal to earth.s radius before returning to the earth. The power exerted by the gravitational force is greatest
Answer» at the highest POSITION of the body at the instant just before the body hits the EARTH it REMAINS CONSTANT all through at the instant just after the body is projected Solution :Power, `P, vecF. vecv = F v cos theta` Just before hitting the earth `theta = 0^@` . Hence, the power exerted by the gravitation force is greatest at the instant just before the body hits the earth.
