Homework Statement
A uniform solid sphere of mass M and radius R is fixed at a distance h above a thin infinite sheet of mass density σ. Obtain the magnitude of the force between the sphere and the sheet.
Homework Equations
The Attempt at a Solution
I've found the gravitational field from the sheet which turned out to be a constant. Now I need the gravitational field of the sphere outside of its radius at a point h. Wouldn't that just be -GM/(R+h)2?
