Homework Answers
One consequence of Newton's law of gravitation is that the gravitational force exerted by a uniform sphere of mass M and radius R on an object outside the sphere (including on its surface) equals the force that would be exerted by a point mass M located at the sphere's center.
Thus, for an object of mass m on the surface, a distance R from the center, the gravitational force exerted by a uniform sphere is:
