Question

The time period of a simple pendulum _______ with the increase in the length of pendulum.

• A. increases
• B. decreases
• C. doesn't change
• D. can't say

Answer 1

The correct option is A increases

Time period $T$ of a simple pendulum is

$T=2\pi \sqrt{\frac{L}{g}}$

Here $L$ is the length of pendulum and $g$ is gravity

So as $L$ increases $T$ also increases
