Newtons' law for Gravitational force F = G M1 M2 / d²
M1 and M2 are masses of two bodies and d is the distance between them.
1) As Force is directly proportional to the mass of each object, the force will be doubled.
2) d is doubled, Force will become 1/4th as Force is inversely proportional to the square of distance.
d is tripled. Force will become 1/9th as force is inversely proportional to the square of d.
3) four times.
