You know that
F = GMm/r^2
so, what happens to F if r is replaced by r/2?
F' = GMm/(r/2)^2 = 4GMm/r^2 = 4F
use the same technique when replacing the other quantities.
Object A experiences a gravitational force due to object B. How would that force change if the separation distance is halved, mA triples, and mB is reduced to one quarter of its original value?
