Question

On the surface of earth the potential energy of body is a)zero b)infinity c)cannot be said d)none of the above​

Answer 1

Answer:

zero

Explanation:

Near the surface of the Earth, the work done in lifting an object through a height h is the product mgh , so U=mgh . The gravitational potential energy, U , of a system of masses m1 and M2 at a distance r using gravitational constant G is U=−Gm1M2r U = − G m 1 M 2 r
