3 long wires are perpendicular
From what I know F = (4pix10^-7)I/(2*pi*r)
The Attempt at a Solution
I'm at a loss for this... but my thoughts on this are: Would each current (I1, I2, I3) have a negative charge and repel the electron out of the plane towards the negative x-axis?
The answer states that it is "out of the page (ie: graph)" and my understanding makes sense, correct?
