1. Newton's law of gravitation stipulates that the attractive force F between two objects of masses M and m at a distance r apart is given by:

F=GMm/r² where G is the gravitational constant.

From the above relation, can you figure out the ratio of the new force after the changes?
(compare with G(2M)m/(2r)²)
