Find out the expression of gravitational potential energy.

Derive an expression for gravitational potential energy of a body at a distance r from earth.

The gravitational field in a region is given by vecE=(5N*kg^(-1))hati+(12N*kg^(-1))hatj (iii) Find the change in gravitational potential energy if a particle of mass 2 kg is taken from the origin to the point (12m,5m).

A thin diamagnetic rod is placed vertically between the poles of an electromagnet . When the current in the electromagnet is switched on , then the diamagnetic rod is pushed up , out of the horizontal magnetic field . Hence the rod gains gravitational potential energy . The work required to do this comes from

At what height above the surface of the earth is the gravitational potential energy of a body equal to that on the surface of the moon ? Assume that the mass of the earth is 80 times that of the moon and the radius of the earth is 4 times that of the moon. Given ,Radius of the earth =6400 km.
