Kepler's third law states that the square of period of revolution (T) of a planet around the sun, is proportional to third power of average distance of r between sun and planet i.e. T^(2) prop k r^(3) where k is constant. If the mass of sun and planet are M, m respectively than as per Newtons law of gravitation force of ttracion, F = (GMm)/(r^(2)). The relation between G & K s describe as
