Along the tangent
Along the radius
Zero
A particle moves with constant speed v along a circular path of radius r and completes the circle in time T. The acceleration of the particle is
(b) The velocity vector of a particle at a point is always along the tangent to the path of the particle at that point.
(c) The acceleration vector of a particle in uniform circular motion averaged over one cycle is a null vector.
