If M is the mass of one body and m is the mass of another body, and their separation is d, then the gravitational force between them is proportional to

The gravitational force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them. This relationship is described by Newton's law of universal gravitation.

Mathematically, the gravitational force (F) between two objects with masses M and m, separated by a distance d, can be calculated using the formula:

F = G * (M * m) / d^2

In this equation, G represents the gravitational constant, which is approximately equal to 6.67430 × 10^-11 m^3 kg^-1 s^-2.

To find the gravitational force between two objects, you need to know the masses of both objects and the distance separating them. Plug these values into the equation mentioned above, and you'll be able to determine the gravitational force between the objects.
