In a certain universe the gravity is a conservative force but not necessarily an inverse square law force In that universe there exists a single point like mass m that is influenced only by gravity As a result of a gravitational force the mass orbits the fixed source point O in a circle so that the source point is on the circle s rim Neglecting the singular point select that correct alternative s r is the distance of m from O Vo P OP 2R 4R V A Velocity of the point mass as function of r is given by r 0 B Force experienced by point mass depends on intial speed V of point mass C Force experienced by point mass will be inversly proportnal to fifth power of its distance from O D Position vector of particle with respect to centre of circle sweeps out equal area in equal interval of time
