The average acceleration vector for a particle having a uniform circular motion is
A
A constant vector of magnitude 
B
A vector of magnitude 
directed normal to the plane of the given uniform circular motion
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
Text Solution
Verified by ExpertsThe correct answer is:
D
In complete revolution change in velocity becomes zero so average acceleration will be zero.
