It is directly proportional to the product of two masses of the bodies and inversely proportional to the square of the distance between the bodies.

Consider ‘M₁’ and ‘M₂’ to be the masses of two bodies and ‘r’ to be the distance between two bodies.

Gravitational force = G*M1M2/r2, where ‘G’ is the universal gravitational constant.

To find the gravitational force between the earth and the sun, we use the same formula and substitute the values.

Mass of the Earth = M1=61024 kg, mass of Sun = M2=21030 kg and the average distance between them is r=1.51011 m.

We know that the value of gravitational constant g = 6.6710-11Nm2/kg2.
