Figures,. Correspond to two circular motions. The radius of the circle, the peirod of revolution, the initial position, and the sense of revolution (i.e. clockwise or anticlockwise) are indicated on each. Obtain the corresponding equations of simple harmonic motions of the revolving particle P in each case.

Explanation

To solve the problem of obtaining the equations of simple harmonic motion (SHM) for two circular motions based on the provided parameters, we will follow a systematic approach for each case.

### Part A:

1. **Identify Given Parameters**:
- Radius (Amplitude, A) = 3 cm
- Period of revolution (T) = 2 seconds
- Sense of revolution = Clockwise
