Two long, parallel wires separated by 2.50 cm carry currents in opposite directions. The current in one wire is 1.25 A, and the current in the other is 3.50 A. (a) Find the magnitude of the force per unit length that one wire exerts on the other. (b) Is the force attractive or repulsive?
a)
Given info: The separation between the two wires is
Explanation:
If the system of the two wires has to be in equilibrium, the repulsive force per unit length on the top wire due to the bottom wire has to be equal to the weight per unit length of the top wire.
Substitute
b)
