Two long, parallel wires, each with a mass per unit length
Chapter 19, Problem 19.105(choose chapter or problem)
Two long, parallel wires, each with a mass per unit length of 40 g/m, are supported in a horizontal plane by 6.0-cmlong strings, as shown in Figure P19.72. Each wire carries the same current I, causing the wires to repel each other so that the angle u between the supporting strings is 16. (a) Are the currents in the same or opposite directions? (b) Determine the magnitude of each current.
