Consider the 2 objects in the pic. They both have the same mass of 200 kg. They both have a radius of 4 meters. However, the object on the right is hollow, with the walls being 2 meters thick. For the gravity equation, and the object on the right, does one use a radius of 4 squared, or the wall thickness of 2 squared?
