medium

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

AIt moves in a circular path

BAcceleration is constant

CKinetic energy is constant

DBoth $(a)$ and $(c)$

(IIT-1987)

Solution

(d) 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.
