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.

C.

its kinetic energy is constant

When a force of constant magnitude acts on the velocity of particle perpendicularly, then there is no change in the kinetic energy of the particle. Hence, kinetic energy remains constant.
