Question

Derive an expression for gravitational potential energy

Answer 1

Answer:

Expression for Gravitational potential energy :-

Gravitational potential at a point is the amount of work to transfer unit mass of a body form infinity to that point in a gravitational field. <br>

<br>i.e.,

<br> i.e.,

<br> Gravitational P.e at a point is defined as the energy acquired by the mass body placed at that point in a gravitational field. <br> i.e.,

<br> 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.
