Gravity field of a hollow planet
A uniform, spherical planet has a spherical space at its center.
The radius of the surface of the planet is Rp= 8.9E7 m (8.9 x 10^7 m).
The radius of the central hollow space is Rh = 6.2E5 m.
The total mass of the planet is M= 7.5E28 kg.
The distance from the center to three designated points are:
Point a is distance Ra= 9.2E8 m from center, outside of the planet.
Point b is distance Rb= 5.8E4 m from center, within the hollow center.
Point c is distance Rc= 7.1E6 m from center. between inner and outer surface.
Find the gravitational field of the planet at each of the three points
