Kepler’s third law states that square of period of revolution $(T)$ of a planet around the sun, is proportional to third power of average distance $r$ between sun and planet, that is, $T^2 = K r^3,$ 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$\\F = \frac{G M m}{r^2},$ here $G$ is gravitational constant.$\\$The relation between $G$ and $K$ is described as
