Question

Kinetic energy of the bob of a simple pendulum is maximum

• A. at the mean position
• B. at the extreme left position
• C. at the extreme right position
• D. none of these

Answer 1

The correct option is A at the mean position

The velocity of bob is zero at extreme position whereas

The velocity of bob is maximum at mean position

$KE=\frac{1}{2}m{v}^2$

So $KE$ is maximum at mean position because velocity is maximum at mean position
