A particle is acted upon b a force of constant magnitude which is always perpendicular to the velocity of the particle. The mootio of the particle takes place in a plane. It follows that (a) Velocity is constant (b) Acceleration is constant(c) Kinetic energy is constant(d) It moves in a circular path

Answer»

Correct Option  (c) Kinetic energy is constant

(d) It moves in a circular path

Explanation:

In the given condition, the particle undergoes uniform circular motion and for uniform circular motion the velocity and acceleration vector changes continuously but kinetic energy is constant for every point
