every object in the universe attracts every other object with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between them.
now according to this force is directly proportional to products of masses and let G =constant.
therefore, F=G×m1×m2.
now it is inversely proportional to the square of distance between them.
therefore, F=1÷R2
from this we get:
F=G×m1×m2÷R2

Statement of Universal Gravitation:
The Law of Universal Gravitation states that every object of mass in the Universe attracts every other object of mass with a force which is directly proportional to the product of their masses and inversely proportional to the square of the separation between their centers.
The proportionalities expressed by Newton's universal law of gravitation are represented graphically by the following illustration. Observe how the force of gravity is directly proportional to the product of the two masses and inversely proportional to the square of the distance of separation.
