The gravitational force between two attracting objects can be solved through the equation,
F = Gm₁m₂ / d²
where m₁ and m₂ are there masses, d is the distance, and G is the gravitational constant. These means that the force is directly related to the masses and inversely to the distance. From the given choices, B will have the greatest energy, followed by C and A, respectively. Lastly, the least force will that be of D.
