Question
Two long parallel copper wires carrying currents in the opposite direction of 5A each. If the wires are separated by a distance of 0.5m then the force between the two wires is:
- 10–5 N/m attractive force
- 10–5 N/m repulsive force
- 2
10–5 N/m attractive force
- 2 10–5 N/m repulsive force
10–5 N/m attractive force
10–5 N/m repulsive force
The correct answer is: 10–5 N/m repulsive force
