Keller's third law states that the square of period of revolution (T) of a planet around the sun is proportional to the sun is proportional to the third power of average distance , r between the sun and the planet i.e T^2 = Kr^3 Here ,K is constant . If masses of the sun and the planet are M and m respectively , then as per Newton's law of gravitation force of attraction between them is F =(GMm)/r^2 , Where G is gravitational constant . The relation between G and K is described as

According to Newton's law of gravitation , the force F between tow bodies of masses m_1 and m_2 placed at a distance of 'r' form each other is given as F = G xx (m_(1)xx m_(2))/r_(2) , where G is the universal gravitional constant. Find the units of G in both C.G.S. and S.I. system.

According to Newton's law of gravitational, every particle of matter attracts every other particle. But bodies on the surface of Earth never move towards each other on account of this force of attraction. Why ?

Suppose that the gravitational force between two bodies separated by a distance R becomes inversely proportional to R (and not as (1)/(R^(2)) as given by Newton's law of gravitation). Then the speed of a particle moving in a circular orbit of radius R under such a force would be proportional to
