उत्तर
Newton’s law of gravitation: States that the gravitational force between two masses is directly proportional to the product of masses and inversely proportional to the square of the distance between the masses.
In the mathematical form, it can be written as,
`vec"F" = -("GM"_1"M"_2)/"r"^2 hat"r"`
