Two long, parallel wires are separated by a distance of 3.40 cm . the force per unit length that each wire exerts on the other is 3.60×10−5 n/m , and the wires repel each other. the current in one wire is 0.640 a

Current in second wire,

Explanation:

It is given that,

Separation between two parallel wire,

Force per unit length each wire exerts on the other is,

Current in wire 1,

Let is the current in other wire. The force acting per unit length is given by :

So, the current in the second wire is 9.562 A. Hence, this is the required solution.
