A particle is moving with uniform speed along a circular path then

detailed solution

Correct option is A

When a particle is moving in a circular path with uniform speed we get following are true.

i) The magnitude of velocity at every point remain constant.

ii) The direction of velocity will be changing continuously from one point to another point.

iii) Average velocity over a period of revolution will be zero because total displacement over a revolution is zero.

iv) Velocity changes along the vector difference of final and initial velocities.

v) Speed remains constant.
