WebStated in modern language, Newton’s universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Figure 2. WebBy Newton Law of Gravitation, F = GMm / r 2. Combining, magnitude of g = GM / r 2. Therefore g = GM / r 2, M = Mass of object “creating” the field. Example 1: Assuming that …
