Question

the magnitude of gravitational force of attraction between two objects is F. if the mass of each object and the distances between them are tripled, then the magnititude of new gravitational force between them is

Answer 1

If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

Answer 2

We know by law of gravitational force,

F = G(m1 *m2)/r^2 where F is the gravitational force, m1 and m2 are the masses of the two objects respectively, r is the radius between the two objects and G is the universal gravitational constant.

So if the masses of the objects and their in between radius are tripled the new gravitational force between them remains m same as before.
