Chapter , Problem 77(choose chapter or problem)
A solid sphere of radius R has its center at the origin. It has a uniform mass density except that the sphere has a spherical cavity in it of radius centered at as in Figure 11-27. Find the gravitational field at points on the x axis for Hint: The cavity may be thought of as a sphere of mass m _ (4>3)pr3r0 plus a sphere of negative mass m. SSM
