Kinematics Question 734
Question: The average acceleration vector for a particle having a uniform circular motion is[Kurukshetra CEE 1996]
Options:
A) A constant vector of magnitude $ \frac{v^{2}}{r} $
B) A vector of magnitude $ \frac{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
Show Answer
Answer:
Correct Answer: D
Solution:
In complete revolution change in velocity becomes zero so average acceleration will be zero.
