The figure shows a cross section of three long, straight, and parallel current- L. carrying wires. Notice we are using the common convention that crosses denote vectors pointing into the page and dots denote vectors coming out of the page. A 5.00 A Part (a) Find the magnitude of the force per unit length, in newtons per meter, on wire A. FA = 10.0 A 10.0 cm 20.0 A Part (b) Find the direction of the force for wire A. Measure this angle counterclockwise, in degrees, from the positive x-axis. 10.0cm 10.0 cm- The figure shows a cross section of three long, straight, and parallel current- L. carrying wires.
