According to Newton's law of universal gravitation,any two particles of finite mass attract each another with a force which is-
1
Inversely proportional to the product of their masses and directly proportional to the square of their distance apart.
2
Inversely proportional to the product of their masses and directly proportional to their distance apart.
3
Directly proportional to the product of their masses and inversely proportional to their distance apart.
4
Directly proportional to the product of their masses and inversely proportional to the square of their distance apart.
