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
If a particle is performing uniform circular motion then, 1) Its speed remains constant throughout the motion. 2)Tangential acceleration is always zero. 3)The magnitude of the radial acceleration is constant always. The magnitude of acceleration remains constant all through the uniform circular motion. So, the correct option is D
