Answer:
Answer
(a) False, the acceleration is towards the centre only in uniform circular motion. In non Uniform motion, acceleration has tangential component as well.
(b) True, the velocity is always tangential, if the motion is uniform or not.
(c) True, When particle returns to its original position after completing one cycle, its displacement is zero. Hence, average velocity and acceleration over one complete cycle is zero, which is null vector.
