Two long straight current-carrying wires run parallel to each other. The current in one of the wires is 4.3 A, their separation is 4.6 cm and they repel each other with a force per unit length of 2.7 x 104 N/m. (a) Determine the current in the other wire. A (b) Determine if the currents are in the same or opposite direction. O opposite O same (c) Determine what will happen if the direction of one current is reversed and tripled. (Select all that apply.) O The force per unit length is increased by a factor of 3. O The force per unit length is decreased by a factor of 3. O The wires are repelled by each other. O The wires are attracted to each other.
