Three long wires are connected to a meterstick and hang down freely. Wire 1 hangs from the 50-cm mark at the center of the meterstick and carries 1.50 A of current upward. Wire 2 hangs from the 70-cm mark and carries 4.00 A of current downward. Wire 3 is to be attached to the meterstick and to carry a specific current, and we want to attach it at a location that results in each wire experiencing no net force. (a) [8 pts.] Determine the position of wire 3. (b) [8 pts.] Determine the magnitude and direction of current in wire 3.
