1. The problem statement, all variables and given/known data

How far from a wire with a current of 5.0A is a second parallel wire with current 10A if force between them is $$3.6x10^{-4} N$$?

2. Relevant equations

i think $$\frac{F}{L}=\left(\frac{u_o}{2\pi}\right)\left(\frac{I_{1}I_{2}}{s}\right)$$

3. The attempt at a solution

i think this just a simple plug and chug question, but is $$\frac{F}{L}$$ equal to $$3.6x10^{-4} N$$? whats the L for?

F/L is force per unit length and yes, here F/l is 3.6x10^{-4}.
