Question

Let the period of revolution of the planet at the distance R.from star to B prove that

Answer 1

Answer:

According to Kepler's third law, The square of orbital period of revolution T of a planet around a star is directly proportional to the cube of the mean distance R of the planet from the star. Thus, for a planet, at a distance of 2R from the star, its period of revolution will be √8 T.
