A particle moves in a circle of radius 1.5m with a speed of 3m/s. What is its centripetal acceleration?
Centripetal acceleration ac=v2R. As per NCERT Chapter 3, equations v=u+at, s=ut+½at², v²=u²+2as describe uniformly accelerated motion. Applying correct signs and units gives 6 m/s² as the result, so option B is correct.
