Choose the correct definition of Universal law of gravitation

• Every object in the universe attracts every other object with a force which is proportional to the product of the distance between them and inversely proportional to their masses

• Every object in the Universe attracts every other object with a force which is inversely proportional to the square of the distance between them and proportional to the product of their masses

• Every object in the universe attracts every other object with a force which is proportional to their masses and inversely proportional to the square of distance between them
