Question

when the body is kept at infinitythe gravitational potential energy is zero. Why? ​

Answer 1

HEY SHREYA

HERE'S YOUR ANSWER

In this case we generally choose the zero of gravitational potential energy at infinity, since the gravitational force approaches zero at infinity. This is a logical way to define the zero since the potential energy with respect to a point at infinity tells us the energy with which an object is bound to the earth.
