Homework Help: Distance separating current carrying wires.

  1. Mar 15, 2007 #1
    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 [tex]3.6x10^{-4} N[/tex]?

    2. Relevant equations

    i think [tex]\frac{F}{L}=\left(\frac{u_o}{2\pi}\right)\left(\frac{I_{1}I_{2}}{s}\right)[/tex]

    3. The attempt at a solution

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

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