A magnetic pole of strength `q_m` is placed at a distance of 20 cm from another magnetic pole of triple its strength. If the two poles exert a force of 2.5 g f on each other, find the strength of each pole.

Explanation

To solve the problem of finding the strengths of two magnetic poles, we will follow these steps:

### Step 1: Understand the Given Information
We have:
- A magnetic pole of strength \( q_m \).
- Another magnetic pole of strength \( 3q_m \) (triple the first).
- The distance between the two poles is \( 20 \, \text{cm} = 0.2 \, \text{m} \).
- The force exerted between the two poles is \( 2.5 \, \text{gf} \).
