1. The problem statement, all variables and given/known data The figure shows a spherical hollow inside a lead sphere of radius R = 4.6 m; the surface of the hollow passes through the center of the sphere and “touches” the right side of the sphere. The mass of the sphere before hollowing was M = 245 kg. With what gravitational force does the hollowed-out lead sphere attract a small sphere of mass m = 20 kg that lies at a distance d = 14 m from the center of the lead sphere, on the straight line connecting the centers of the spheres and of the hollow? 2. Relevant equations 3. The attempt at a solution when i find the mass of the "hollowed out" sphere its much larger than the larger sphere. I dont know how else to approach this problem.
