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 distace r between the sun and planet i.e. `T^(2) = Kr^(3)`, here K is constant. If the masses of the sun and planet are M and m respectively, then as per Newton's law of gravitationa force of attraction between them is `F = (GMm)/(r^(2))`, hence 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`
