The angle between velocity and acceleration of a particle describing uniform circular motion is

Options

A. `45^(@)`
B. `60^(@)`
C. `90^(@)`
D. `180^(@)`

Answer

C

Explanation

When an object follows a circular path at a constant speed, the motion of object is called uniform circular motion.
Althought the speed does not vary the particle is accelerating because the velocity its direction at every point on circular track.

The acceleration is centripetal, which is perpendicular to motion at every point and acts along theradius and directed towards the centre of the curved circular path.
