What is the ratio of electric and magnetic forces between two moving charges?

Explanation

To find the ratio of electric and magnetic forces between two moving charges, we can follow these steps:

### Step 1: Write the expression for electric force
The electric force (\(F_e\)) between two point charges \(q_1\) and \(q_2\) separated by a distance \(r\) is given by Coulomb's law:
\[ F_e = \frac{1}{4 \pi \epsilon_0} \frac{q_1 q_2}{r^2} \]
