# The Distance Between Two Bodies is Doubled. How is the Magnitude of Gravitational Force Between Them Affected? - Physics

The distance between two bodies is doubled. How is the magnitude of the gravitational force between them affected?

#### Solution

Force of gravity:

F = (Gm_1m_2)/r^2

It is given that r2 = 2r1

:.F_2/F_1 = r_1^2/r_2^2 = r_1^2/(4r_1^2) = 1/4

:. F_2 = 1/4 F_1

Therefore, the force of gravity is reduced four times.
