The ratio of the binding energies of a stationary body at height equal to the radius of the earth and on its surface is

The acceleration due to gravity on the Earth's surface is about 6 times that on the Moon. The radius of the Moon is nearly (4)/(18) times that of the Earth. The ratio of the binding energy of a body at rest on the Earth's surface to that on the Moon's surface is about

The acceleration due to gravity on the surface of the earth is g. If a body of mass m is raised from the surface of the earth to a height equal to the radius R of the earth, then the gain in its potential energy is given by
