A simple pendulum is constructed by attaching a bob of mas m to a string of length L fixed at its upper end. The bob oscillates in a vertical circle. It is found that the speed of the bob is v when the string makes an angle `theta` with the vertical. Find the tension in the string at this instant.

Explanation

To find the tension in the string of a simple pendulum when the bob is at an angle θ with the vertical, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Forces Acting on the Bob**:
- The gravitational force acting downward is \( mg \) (where \( m \) is the mass of the bob and \( g \) is the acceleration due to gravity).
- The tension in the string, \( T \), acts along the string towards the pivot point.
