उत्तर
The gravitational force between two bodies is directly proportional to the product of the masses of those bodies and is inversely proportional to the square of the distance between them.
Explanation:
If the separation r is doubled, the force falls to one quarter `(1/2^2)`, showing the inverse-square dependence. The constant G is the universal gravitational constant that sets the force scale.
