Pressure on a Sphere due to an Interior Force

  1. Jul 31, 2011 #1
    Consider a sphere of mass M and radius R. The interior of the sphere is a uniformly distributed mass M.

    The surface shell of the sphere has a certain mass dm. What is the pressure on the surface of the sphere due to gravitational forces?

    wouldnt the pressure just be the weight per surface area?

    the weight is just the mass times the gravitational force.

    the area is easy to calculate
