1. The problem statement, all variables and given/known data A sphere of radius R contains two spherical cavities. Each cavity has a radius of R/2 and touches both the outside surface of the sphere and its center as shown. The mass of a similar sphere without the cavities is M. Find the force of attraction on a small particle of mass m located on the x - axis a distance d > R from the center of the sphere. 2. Relevant equations g=GMm/R2 3. The attempt at a solution Will upload picture and solution.
