Kinematics Question 787

Question: If $ a _{r} $ and $ a _{t} $ represent radial and tangential accelerations, the motion of a particle will be uniformly circular if[CPMT 2004]

Options:

A) $ a _{r}=0 $ and $ a _{t}=0 $

B)$ a _{r}=0 $ but $ a _{t}\ne 0 $

C) $ a _{r}\ne 0 $ but $ a _{t}=0 $

D) $ a _{r}\ne 0 $ and $ a _{t}\ne 0 $

Show Answer

Answer:

Correct Answer: C

Solution:

In uniform circular motion tangential acceleration remains zero but magnitude of radial acceleration remains constant.
