Keplers Third Law States That Square Of Period Of Revolution Physics QuestionKeplers Third Law States That Square Of Period Of Revolution Physics Question

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 i.e. T²=Kr³ 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/r², here G is gravitational constant. The relation between G and K is described as

Options

(a) GMK=4π²
(b) K=G
(c) K=1/G
(d) GK=4π²
