a) Explanation Given info: The separation between the two wires is 2.50 cm . The wires carry current in opposite direction. Current in one wire is 1.25 A and in the other is 3.50 A . 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. F l = μ 0 I 1 I 2 2 π d F l is the weight per unit length I 1 is the current in the one wire I 2 is the current in the second wire d is the distance between the wires μ 0 is the permeability of free space Substitute 4 π × 10 − 7 T ⋅ m ⋅ A -1 for μ 0 , 2.50 cm for d , 1.25 A for I 1 , 3 b) To determine Whether the force between the wires is attractive or repulsive.
