Read each statement below carefully 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 particle in circular motion is always along the radius of the circle towards the centre only in case of uniform circular motion .
(b) True . The particle always moves tangentially to the circular path.
(c) True. The acceleration vector is directed towards the centre of circle in uniform circular motion and its direction is constantly changing with time . The resultant of all these vectors is a zero vector .
