The gravitational self energy U fo a uniform solid sphere is equal to the amount of work done in assembling together its infinitessimal particles initally lying infinite distance apart IF M is the mass and R is the radius of the solid sphere, then the gravitational self energy of a solid sphere is given by

The gravitational self energy U fo a uniform solid sphere is equal to

1.	The gravitational self energy U fo a uniform solid sphere is equal to the amount of work done in assembling together its infinitessimal particles initally lying infinite distance apart IF M is the mass and R is the radius of the solid sphere, then the gravitational self energy of a solid sphere is given by
