Vedclass · Answer

(C) In uniform circular motion,the speed of the particle remains constant. Tangential acceleration ${a_t}$ is responsible for the change in the magnitude of velocity (speed). Since the speed is constant in uniform circular motion,${a_t} = 0$. Radial (or centripetal) acceleration ${a_r}$ is responsible for the change in the direction of velocity. Since the particle is moving in a circle,its direction changes continuously,so ${a_r} 
eq 0$. Therefore,the condition for uniform circular motion is ${a_r} 
eq 0$ and ${a_t} = 0$.

If ${a_r}$ and ${a_t}$ represent radial and tangential accelerations,the motion of a particle will be uniformly circular if
