For an oscillating simple pendulum is the tension in the string constant throughout the oscillation ? If not, when is it (a) the least (b) the greatest?

Explanation

To determine whether the tension in the string of an oscillating simple pendulum is constant throughout the oscillation, we need to analyze the forces acting on the pendulum bob at different positions during its motion.

### Step-by-Step Solution:

1. **Understanding the Forces**:
- The forces acting on the pendulum bob are the gravitational force (weight) acting downward, which is equal to \( mg \), where \( m \) is the mass of the bob and \( g \) is the acceleration due to gravity.
- The tension \( T \) in the string acts upward along the string.
