Two long straight current-carrying wires run parallel to each other. The current in one of the wires is 4.8 Amp, their separation is 4.9 centimeter and they repel each other with a force per unit length of 2 x 10-4 N/m.
(a) Compute the current in the other wire.
(c) Explain what will happen if the direction of one current is reversed and tripled. (Select all that apply.)
