Two magnetic poles, one of which is four times stronger than the other, exert a force of `10gf` on each other, when placed at a distance of `10cm` in air. Find the strength of each pole.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Define the strengths of the magnetic poles
Let the strength of the weaker pole be \( m \). Then, the strength of the stronger pole will be \( 4m \).

### Step 2: Convert the force from gf to Newton
The force exerted between the two poles is given as \( 10 \, \text{gf} \). We need to convert this into Newtons.
