Read each staremnt below crefully and state, with reasons, if it is true or false : (a) The net acceleration of a particle in circular motion is always along the radius of the circle towards the centre.
(b) The velocity vector of a particle at a point is always aling the tagent to the path of the partile at that point. ltbRgt (c ) The acceleration vector of a particle in uniform circular motion acraged over one cycle is a null vector.

Explanation

(a) False. The net acceleration of a particle is towards the centre only in case of a uniform circulat motion.
(b) True, because while veaving the circular path, the particle moves tagentially to the circualr path.
(C ) True. The direction of accelration vector in a uniform circular motion is directed towards the centre of circular path. It is constantly changing with time. The resulatnt of all there vectors will be a zero vector.
