    Is the acceleration of particle in uniform circular motion constant or vartiable?

    Is the acceleration of a particle in circular motion not always towards the centre. Explain.

    Assertion:- A particle is moving in a circle with constant tangential acceleration such that its speed v is increasing. Angle made by resultant acceleration of the particle with tangential acceleration increases with time. Reason:- Tangential acceleration =|(dvecv)/(dt)| and centripetal acceleration =(v^(2))/(R)
