Homework Statement
You are given 3 wires parallel to each other
(1)------> I
(2)<-------I
(3)------->I
http://www.webassign.net/knight/p32-38alt1.gif (not sure it this link works)
I1=I2=I3 = 16A
the distance between the wires is d=2cm
length of the wires is l= 50cm
Homework Equations
I assume I need to use the μ0 * I1*I2*l/(2∏*d)
The Attempt at a Solution
I calculated that the middle wires force is 0
but for the first wire I tried solving for the force for 1 on 2 and then 1 on 3 and subtracting them because wire 2 repels wire 1 and wire 3 attracts wire 1 I ended up with:
Force 1 on 2 = .0128 N
Force 1 on 3 = .0064 N
I am pretty sure I converted the units correctly but the answer is wrong. Please help.
