## Question

The radius of earth is 6400 km and mass is kg. What will be the gravitational potential energy of a body of 200 kg placed at a height of 600 km from the surface of the earth?

.

### Solution

The gravitational potential energy of a body of mass *m* placed at a height *h*from earth’s surface is given by

Where *M _{e}* and

*R*are respectively the mass and the radius of the earth. Substituting the given values

_{e}
