## Homework Statement

Two long parallel wires carry currents of 2.03 A and 8.83 A. The magnitude of the force per unit length acting on each wire is 4.49*10^5 N/m. Find the separation distance of the wires expressed in millimeters.

## Homework Equations

I'm not entirely sure.

## The Attempt at a Solution

I thought that I would need to use the formula:

I don't have L however, so how do I solve for d?
