The field intensities of two points on the axial line of a bar magnet at distances of `10xx 10^(-2) m and 15 xx 10^(-2) m` are in the ratio 5.8:1. Find the distance between the two poles of the magnet.

Explanation

To solve the problem, we need to find the distance between the two poles of a bar magnet given the ratio of the magnetic field intensities at two points along the axial line of the magnet.

### Step-by-Step Solution:

1. **Understanding the Magnetic Field Intensity**:
The magnetic field intensity (B) at a point on the axial line of a bar magnet can be given by the formula:
\[
B = \frac{\mu_0}{4\pi} \cdot \frac{2M}{d^3}
