Question: two power cables are parallel to each other with their currents running in opposite directions. The magnitudes of the currents in the cables are 4

two power cables are parallel to each other with their currents running in opposite directions. The magnitudes of the currents in the cables are 40A and 65A. The distance between the cables is 0.31 m. What is the magnitude of the force per length between the two cables, and is it attractive or repulsive?
