MCQ
The velocity of simple pendulum is maximum at
  • A
    Extremes
  • B
    Half displacement
  • Mean position
  • D
    Every where

Answer

Correct option: C.
Mean position
c
(c) The velocity of bob is zero at extreme position whereas

The velocity of bob is maximum at mean position

$K E=\frac{1}{2} m v^{2}$

So $K E$ is maximum at mean position because velocity is maximum at mean position
