It is well known that each and every mass produces a gravitational field of its own in the surrounding region. The magnitude of this gravitational field, at any point, is taken as a measure of the gravitational intensity (of its gravitational field) at that point Consider a system of three identical point masses, each of mass m, located at the three vertices of an equilateral triangle of side r, Each of these point masses will exert a gravitational force on the other two point masses. The magnitude and directions of all these forces is given by Newton's law of gravitation. |
