JEE Main level, single correct, medium

32 of 183

Question 32 of 183

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

Show answer and solution

Answer: (C) its kinetic energy is constant

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.
