The force of gravity varies by the **square **of the **inverse **(or ** RECIPROCAL**) of the distance.

A) If the distance is multiplied by 3, the force between them is multiplied by 1/9.

B) If the distance is one half of the original distance, the force between them is multiplied by 2.

So **(a) is 1/9** and** (b) is 2**.
