A uniform, solid, l00-kg sphere has a radius of 5.00 m.
(a) Find the gravitational force this sphere exerts on a 2.00-kg point mass placed at the following distances from the center of the sphere: (i) 5.01 m, and (ii) 2.50 m.
(b) Sketch a qualitative graph of the magnitude of the gravitational force this sphere exerts on a point mass m as a function of the distance r of m from the center of the sphere. Include the region from r = 0 to r = 0 to r(.
