The magnitude of the gravitational force between two objects can be expressed by

$(Gm_1 m_2)/r^2$ , where

$G$ is the gravitational constant,

$m_1, m_2$ are the masses of the two objects, and

$r$ is the distance between them. If the distance between the objects decreases by a factor of 2, what happens to the magnitude of the gravitational force?

It decreases by a factor of $4.$
It decreases by a factor of $2.$
It decreases by a factor of $sqrt(2)$ .
It increases by a factor of $4.$
