A sphere of radius has a concentric spherical cavity
Chapter 8, Problem 8.60(choose chapter or problem)
A sphere of radius has a concentric spherical cavity ofradius r2 (Fig. 8-40). Assume this spherical shell of thicknessri - r2 is uniform and has a total mass M. Show that thegravitational potential energy of a mass m at a distance r fromthe center of the shell(r > Tx) is given byU = -GmMFIGURE 8-40 60.
