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)`
