Every body in the universe attracts every other body with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The force acts between the line joining the two bodies. Which law is this?
Universal Law of Gravitation
Universal Law of Attraction
Universal Law of Repulsion
Law of Conservation of Energy
