Question

If the amplitude of a simple pendulum is doubled, how many times will the value of its maximum velocity be that of the maximum velocity in initial case.

• A. 1/2
• B. 2
• C. 4
• D. 1/4

Answer 1

The correct option is C 4

The time period remains the same,

if ${}^{\prime }{\omega }^{\prime }$ $\left(omega\right)$ ramins the same.

The maximum velocity gets doubled$.$

The maximum acceleration gets doubled$.$

total energy increases $4$ times$.$

Hence,

option $\left(C\right)$ is correct answer.
