Answer:
If the mass of the object is doubled , then the force of gravity between them is doubled ..... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects , more separation distance will result in weaker gravitational forces.

Explanation:
when doubled the the gravitational force between two objects is increased by 1/4
F=GMm/r^2
when r is doubled=
F=GMm/(2r)^2
=F=GMm $4r^2
Same way
when r is reduces to half
F=GMm/(r/2)^2
=F=GMm/r^2/4
=4×GMm/r^2
=F=4F
therefore when distance is reduced to 1/2 F is increased by 4
