What is the percentage change in the time period, if the length of simple pendulum increases by `3%`.

Explanation

To find the percentage change in the time period of a simple pendulum when the length is increased by 3%, we can follow these steps:

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