36. Using Eq. 29-13, the force on, say, wire 1 (the wire at the upper left of the figure) is along the diagonal (pointing towards wire 3 which is at the lower right). Only the forces (or their components) along the diagonal direction contribute. With θ= 45°, we find the force per unit meter on wire 1 to be ()22200011213141213223||2cos2cos 452224T m A 15.0A31.12N/m.8.50 10 miii
