Question

What happens to force between two bodies if

1.The mass of one body is doubled

2.The masses of both the bodies are tripled

3.The distance between two bodies is tripled

Answer 1

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)force will be four times the old force

3) d is tripled. Force will become 1/9th as force is inversely proportional to the square of d.
