  • 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 means T^2 = Kr^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 = (GMm)/r^2 , here G is gravitational constant the relation between G and K is described as

    A
    `GK = 4pi^2`
    B
    `GMK = 4pi^2`
    C
    `K=G`
    D
    `K = 1/G`
