Imagine a light planet revolving around a very massive star in a circular orbit of radius R with a period of revolution T. If the gravitational force of attraction between the planet and the star is proportional to R-5/2, then, |
T2 is proportional to R2 T2 is proportional to R7/2 T2 is proportional to R3/2 T2 is proportional to R3.75 |
T2 is proportional to R7/2 |
mRω2 ∝ R−5/2 ⇒ T2 ∝ R7/2 |
