Question

A constant force is acting upon a particle that is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane and it is known as uniform circular motion. Which of the following statements is correct for uniform circular motion? (A) Velocity of the particle is constant. (B) Acceleration of the particle is constant. (C) Kinetic energy of the particle is constant. (D) Work done by perpendicular force on the particle is non-zero.
​

Answer 1

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.
