For a particle performing uniform circular motion, choose the correct statement (s) from the following.

Magnitude of particle velocity (speed) remains constant

Particle velocity remains directed perpendicular to radius vector

direction of acceleration keeps changing as particle moves

Tangential acceleration of the particle is non zero.

Text Solution

Verified by Experts

The correct Answer is:

A, B, C

For a particle performing uniform circular motion.
(i) speed will be constant throughout.
(ii) veclocity will be tangential in the direction of motion at a particular point.
(iii) acceleration`a=(v^2)/(r )` will always be towards centre of the circular path
(iv) Speed is constant, hence tangential acceleration is zero.
