Two particles start moving from same position on a circle of radius 20 cm with speed `40 pi` m/s and `36pi` m/s respectively in the same direction. Find the time after which the particles will meet again.

Explanation

To solve the problem, we need to find the time after which two particles moving in the same direction on a circular path will meet again. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the given values
- Radius of the circle (r) = 20 cm = 0.2 m (convert to meters)
- Speed of the first particle (V1) = 40π m/s
- Speed of the second particle (V2) = 36π m/s

### Step 2: Calculate the difference in speed
