When will the motion of a simple pendulum be simple harmonic?

Explanation

To determine when the motion of a simple pendulum is simple harmonic, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Simple Harmonic Motion (SHM)**:
- Simple harmonic motion is defined as a type of periodic motion where the restoring force is directly proportional to the displacement from the equilibrium position and acts in the opposite direction.

2. **Analyzing the Pendulum**:
