In each hand you hold a 0.15 kg apple.
What is the gravitational force exerted by each apple on the other when their separation is 0.25 m?
What is the gravitational force exerted by each apple on the other when their separation is 0.50 m?

Force=GM1M2/distance^2
Notice if you figure one, the next distance is twice, so force is 1/4 of the original.
