Question

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, its velocity is constant, its acceleration is constant, its kinetic energy is constant, it moves in a straight line.

MARKS App · Accepted Answer

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