Two meter-long parallel wires each have a linear mass density λm = 30 g/m and carry the same current I. They are hung from the same support bar by strings of length L = .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? Please show all work and equations used with given values.
