How does the time period (T) of a simple pendulum depend on its length (l)? Draw a graph showing the variation of `T_2` with l. How will you use this graph to determine the value of g (acceleration due to gravity) ?

Explanation

To solve the question regarding how the time period (T) of a simple pendulum depends on its length (l), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Relationship**:
The time period (T) of a simple pendulum is given by the formula:
\[
T = 2\pi \sqrt{\frac{l}{g}}
