Three very long wires are strung parallel to each other as shown in the gure below. Each wire is at a distance 46 cm from the other two, and each wire carries a current of magnitude 1' = 2.9 A in the directions shown in the gure. 3 QI y (9 (9 z 1 H 46 cm "'4 2 Crosssectional View Find the magnitude of the net force per unit length exerted on the upper wire (wire 3) by the other two wires. Answer in units of N /m. 022 (part 2 of 2) 10.0 points What angle does the net force on the upper Wire (Wire 3) make with the positive air-axis? Measure your angles in the standard way: counter-clockwise from the positive maxis. 1. 6 = 180 2. 6 = 240 3. 6 = 00 4. 6 = 120 5. 6 = 210 6. 6 2 270 7. 6 = 60 8. 6 = 30 9. 6 2 300 10. 6 = 0
