Question

Two unequal point masses attract each other with a force F when they are located a distance (d) apart. what force (in terms of F) will they exert on each other if the mass of one of them is tripled but the distance does not change, both masses are tripled, the masses stay the same but the distance between them is doubled, both masses are doubled, both masses are doubled and the the distance between them is cut in half, and how far apart should these masses be so that the original force will be reduced by 1/2?
