Question

Derive an expression for the gravitational potential energy of a body m located at a

distance r from the centre of the earth​

Answer 1

Gravitational P.e at a point is defined as the energy acquired by the mass body placed at that point in a gravitational field. where M = mass of the Earth , m = mass of a body above the surface of the Earth , r = R + h where r = radius of the Earth , h = height of the mass body above the surface of the Earth.
