At what point in the motion of a simple pendulum is the string tension greatest ? At what point is it least? What in case of a conical pendulum?

Explanation

### Step-by-Step Solution

1. **Understanding the Simple Pendulum**:
- A simple pendulum consists of a mass (bob) attached to a string of length \( L \), which swings back and forth under the influence of gravity.
- The forces acting on the bob are its weight \( mg \) (acting downwards) and the tension \( T \) in the string.

2. **Identifying Positions**:
- The pendulum has two significant positions: the **lowest point** (equilibrium position) and the **highest points** (extreme positions).
