The force per meter between the two wires of a jumper cable being used to start a stalled car is 0.335 N/m.
Required:
a. What is the current in the wires, given they are separated by 2.90 cm?
b. Is the force attractive or repulsive?
1. The force is repulsive because the currents are in opposite directions.
2. The force is repulsive because the currents are in the same direction.
3. The force is attractive because the currents are in the same direction.
4. The force is attractive because the currents are in opposite directions.
