The gravitational force between two objects varies directly as their masses and inversely as the square of the distance between them.

F = G × m1 × m2

r²

So, when the masses of both objects are doubled without changing the distance

F =G × 2m1 × 2m2

r²

The gravitational force between them would become four times of the original value.

F = 4 × G × m1 × m2

r²

Mark it as brainliest answer dude.
