Two meter-long parallel wires each have a linear mass density of 30 g/m and carry the same current of 0.50 mA. The are hung from the same support bar by strings of length .080 m so that the wires run parallel to the ground. The current causes the wires to repel from each other, so they hang with an angle θ = 20◦ between the supporting strings of the two wires. Are the currents in the same or opposite directions? What is the magnitude of the current?
