###### FREE Expert Solution

We are required to explain the effect of distance on the gravitational force.

Newton's law of gravity:

$\overline{){\mathbf{F}}{\mathbf{=}}\frac{\mathbf{G}\mathbf{M}\mathbf{m}}{{\mathbf{R}}^{\mathbf{2}}}}$G is the gravitation constant, M is the mass of the first object, m is the mass of the second object, and R is the separation between the masses.
