1. Kepler’s third law states that square of period of revolution (T) of aplanet around the sun, is proportional to third power of average distance r between sun and planet i.e.\(T^2 = K r^3\) here K is constant. If the masses of sun and planet are M and m respectively then as per Newton’s law of gravitation force of attraction between them is \(F = \frac{GMm}{r^2}\), here G is gravitational constant.The relation between G and K is described as
