Two horizontal parallel straight conductors, each 20 cm long, are arranged one vertically above the other and carry equal currents in opposite directions. The lower conductor is fixed while the other is free to move in guides remaining parallel to the lower. If the upper conductor weighs 1.0 g, what is the approximate current (in A) that will maintain the conductors at a distance 0.50 cm apart?
