If the motion of revolving particle is perodic in nature, give the nature of motion or projection of the revolving particle along the diameter.

Explanation

To solve the question, we need to analyze the motion of a particle that is revolving in a circular path and determine the nature of its projection along the diameter.

### Step-by-Step Solution:

1. **Understanding Circular Motion**:
- A particle moving in a circular path with a constant radius \( r \) is undergoing circular motion. This motion is periodic, meaning it repeats itself after a fixed time interval known as the time period \( T \).

2. **Periodic Nature of Circular Motion**:
