Imagine a light planet revolving around a very heavy star in a circular path. The radius of the orbit =R and the time period of revolution =T. if the gravitational force of attraction between the star and the planet is directly proportional to R^(-5//2) , then the relation between T and R would be T^2 prop R^n . Determine the value of n.
