A particle of mass m carrying charge `'+q_(1)'` is revolving around a fixed charge `'-q_(2)'` in a circular path of radius r. Calculate the period of revolution.

Explanation

To calculate the period of revolution of a particle of mass \( m \) carrying charge \( +q_1 \) revolving around a fixed charge \( -q_2 \) in a circular path of radius \( r \), we can follow these steps:

### Step 1: Identify the Forces Acting on the Particle
The particle experiences two main forces:
1. **Centripetal Force**: This is required to keep the particle moving in a circular path and is given by:
\[ F_c = \frac{mv^2}{r} \]
