Give the law of gravitation of Newton.

Explanation

Each object of this world attracts other objects towards itself. This force is directly proportional to masses of two objects and inversely proportional to square of distance between them.
`F = (Gm_(1)m_(2))/(r^(2))`
(G = Universal gravitation constant = `6.67 xx 10^(-11) Nm^(2)//kg^(2)`)
