Question:
For a particle performing uniform circular motion, choose the correct statement from the following:
(a) magnitude of particle velocity (speed) remains constant
(b) particle velocity remains directed perpendicular to radius vector
(c) direction of acceleration keeps changing as particle moves
(d) angular momentum is constant in magnitude but direction keep changing
Solution:
The correct answer is (a) magnitude of particle velocity (speed) remains constant, (b) particle velocity remains directed perpendicular to radius vector and (c) direction of acceleration keeps changing as particle moves
