For a particle in a uniformly accelerated circular motion

A)  velocity is radial and acceleration has both radial and transverse components

B)  velocity is transverse and acceleration has both radial and transverse components

C)  velocity is radial and acceleration is transverse only

D)  velocity is transverse and acceleration is radial only

Correct Answer: A

Solution :

                 When a particle moves in a uniformly  accelerated circular motion, then its direction changes continuously though its speed remains constant. Thus, its velocity   changes   continuously and it has two components of acceleration, one radial \[({{a}_{R}})\] and the other transverse \[({{a}_{T}})\].
