Maths Physics Question
(taken from Modern Pypsics by Rohlf, Ch 1, Qs 46)

Show that the gravitational binding energy (Eb) of a uniform sphere of mass M and radius R (and where G is the gravitational constant) is

Eb = (3*G*(M^2))/(5*R)

(Hint: Start with an infinitesimal mass dM and calculate the energy released as mass is brought in from infinity.)
