Question

what is the universal gravitetion law ?

Answer 1

Newton's law of universal gravitation states that a particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.[note 1] This is a general physical law derived from empirical observations by what Isaac Newton called inductive reasoning.

Answer 2

According to universal law of gravitation....... Every object in the universe either attract each other, with the force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

F= G× m1×M2/r^2
