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