According to the universal law of gravitation, gravitational force exerted on an object of mass m is given by:

The Universal Law of Gravitation states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This is often written in mathematical form as:

F = G * (m1*m2) / r^2

Where:

• F is the force of attraction between the two bodies,
• m1 and m2 are the masses of the two bodies,
• r is the distance between the centers of the two bodies,
• G is the gravitational constant.

So, the gravitational force exerted on an object of mass m (let's say m1) by another object of mass m2 would be calculated using the above formula.
