A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that

A

its velocity is constant

B

its acceleration is constant

C

its kinetic energy is constant

D

its moves in a circular path

Text Solution

Verified by Experts

The correct Answer is:
C, D
The given case is of uniform circular motion, in which speed of particle remains constant. Direction of velocity and acceleration keep on changing although its magnitude remains constant.
