1 and m 2 the particles masses, and r the distance between them Equation (5 1) is however not complete since the force due to gravitation is vectorial in nature If we define the vectors r 1 and r 2 for the positions of m 1 and m 2, respectively, and the unit vector that points from r 1 to r 2 is e r=(r 2−r 1)r 2−r 1, then the force that m

also realize how weak the force of gravitation is, when you lift a small stone or when a charged comb picks up small pieces of paper However, the force of gravitation becomes appreciably stronger if masses of the objects are increased Example 11 1: A boy of 40 kg mass is standing on the surface of earth If the mass

F∝M × m (10 1) And the for ce between two objects is inversely pr oportional to the square of the distance between them, that is, ∝ 2 1 F d (10 2) Combining Eqs (10 1) and (10 2), we get F ∝ 2 M m× d (10 3) or, G 2 M × m F = d (10 4) where G is the constant of pr oportionality and is called the universal gravitation constant By

Chapter 6 Gravitation and Newton’s Synthesis
6-1 Newton’s Law of Universal Gravitation Therefore, the gravitational force must be proportional to both masses By observing planetary orbits, Newton also concluded that the gravitational force must decrease as the inverse of the square of the distance between the masses In its final form, the law of universal gravitation reads: where
