If the distance between the two objects increase, what will happen to the force of gravity? Question 7. In modern language, the law states: Every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The distance between a 40-kg person and a 30-kg person is 2 m. What is the magnitude of the gravitational force each exerts on the other. He came up with the universal law of gravitation. Which of the following represents the gravitational force at this distance? Answer. The test for the Universal Law of Gravitation was performed through experimental observation of the motion of planets, which turned out to be resoundingly successful. Law of gravitation gives the gravitational force between (a) the Earth and a point mass only (b) the Earth and Sun only (c) any two bodies having some mass (d) two charged bodies only. But it's important to realize that the distance between the two objects, especially when we're talking about the universal law of gravitation, is the distance between their center of masses.
