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 kinetic energy is constant

C

it moves in a circular path

D

Both b and c are correct

Text Solution

Verified by Experts

The correct Answer is:
D
A force of constant magnitude which is always perpendicular to the velocity of the particle dose not do work. Hence, KE of the particle is constant. As force is perpendicular to the velocity, the particle moves in a circular path.
