How would the force of gravity between two masses be affected if the separation distance between them were the following? (Assume F2 represents the new force and F1 represents the original force.)

Question

(a) triple the original distance
F2 / F1 =
(b) one-fourth the original distance
F2 / F1 =

Answer 1

((1/3)^2 = 1/9

4^2 = 16
