What will be the time period of second's pendulumm if its length is doubled?

Explanation

To find the time period of a second's pendulum when its length is doubled, we can follow these steps:

### Step 1: Understand the formula for the time period of a pendulum
The time period \( T \) of a simple pendulum is given by the formula:
\[ T = 2\pi \sqrt{\frac{L}{g}} \]
where:
