## Homework Statement

The magnitude of the magnetic force between two conductors 4.00m long, separated by 8.00cm is, 2.85X10^-5 N. The current in one conductor is twice the current in the other. Calculate both currents.

Given: FM = 2.85X10^-5 N

l = 4.00m

Mo = 4pie X10^-7

d = 0.08m

I2 = 2(I1)

I1 = ?

## Homework Equations

F2/l = Mo(I1)(I2)/2pie(d)

## The Attempt at a Solution

Couldnt really understand how I am supposed to find one of the currents when i don't know either of them, if i knew one i could find it easily.
