Q.

A particle moving with uniform speed in a circular path maintains:

  1. A

    constant velocity but varying acceleration.

  2. B

    varying velocity and varying acceleration

  3. C

    constant velocity

  4. D

    constant acceleration

Solution

In uniform circular motion the speed is constant but the velocity vector changes direction every instant, so velocity is varying.

The centripetal acceleration has constant magnitude but its direction (always toward the centre) also rotates with the particle, so acceleration is varying as a vector too.
