A particle is acted upon by a force of constant magnitude which is always is perpendicular to the velocity of the particle , the motion of the particles takes place is a plane it follow that

A

its kinetic energy is constant

B

its acceleration is constant

C

its velocity is constant

D

it moves in a straight line.

Text Solution

Verified by Experts

The correct Answer is:

A

When a force of constant magnitude which is perpendicular to the velocity of particle acts on a particle, work done is zero and hence change in kinetic energy is zero.
