Assertion : If both the speed of a body and radius of its circular path are doubled, then centripetal force also gets doubled. Reason : Centripetal force is directly proportional to both speed of a body and radius of circular path.

In doubling the mass and acceleration of the mass, the force acting on the mass with respect to the previous value
