When the distance between the two objects is halved, the gravitational force becomes four times. ProofAccording to the universal law of gravitation The gravitational force F between the two bodies of masses M and m is kept at a distance d from each other such that:; F = G (m1.m2/r2) Where, m1 and m2 are the masses of the two bodies. G is the gravitational constant. r is the distance between the two bodies. Given that the distance is reduced to half then, r = 1/2 r While the force between the two bodies is inversely proportional to the square of the distance between them which is given as: F = G (m1.m2/(r/2)2) F= 4G m1.m2/ r2 Therefore, when the distance is halved, the gravitational between these two bodies becomes four times
