2 identical wires have a weight per unit length of 1.0 x 10^-4 N/m. The wire are strug parallel to each other one directly above the other with a distance of separation of 0.10m. What current must be present in the 2 wires in order for the upper wire to float above the lower wire. Assume that the wires carry the same current in opposite directions.
