.

(a)  If the new separation distance is  1%2F3  of the previous distance, new gravitation force is 9 times of that in previous case.



(b)  If the new separation distance is  3 times  the previous distance, new gravitation force is  1%2F9  of that in previous case.



These facts are the simple and direct consequences of the Newton's gravity law.
