A particle is moving with a constant angular acceleration of 4rad//s^(2) in a circular path. At time t=0 , particle was at rest. Find the time at which the magnitudes of centripetal acceleration and tangential acceleration are equal.

Two bodies having masses 10kg and 5kg are moving in concentric orbits of radii 4 and 8 such that their time periods are the same. Then the ratio of their centripetal accelerations is

Assertion: Centripetal acceleration is always direction towards the centre of rotation of an object undergoing uniform circular motion Reason: Centripetal acceleration is a constant vector
