The average acceleration vector for a particle having a uniform circular motion is
A constant vector of magnitude $\frac{{{v^2}}}{r}$
A vector of magnitude $\frac{{{v^2}}}{r}$ directed normal to the plane of the given uniform circular motion
Equal to the instantaneous acceleration vector at the start of the motion
A null vector
The average acceleration vector for a particle having a uniform circular motion is
In complete revolution change in velocity becomes zero so average acceleration will be zero.
