Question

According to the universal law of gravitation two objects attract each other with equal force

Answer 1

according to universal law of gravitation force of gravitation between two object is directly proportional to the product of their masses and inversely proportional to the square of the distance between them .
if a and b be two objects of masses M1 and M2 respectively and Didi distance between their Centre then gravitational force between them
f is directly proportional to m1m2/d2 or f=Gm1m2/d2

Answer 2

Newton's law of universal gravitation states that every 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.

The equation for universal gravitation thus takes the F=G(m1×m2)/d2
