Question $12$

Consider two parallel current$-$carrying conductors $($wires$)$ with the currents following in the same direction. Which of the following is FALSE?The magnitude of the force exerted by one wire on the other one is proportional to the currents on the wires.The magnitude of the force exerted by one wire on the other one is inversely proportional to the distance between the wires.The forces per unit length that the wires exert on each other are the same in magnitude.The forces that the wires exert on each other are the same in direction.
