Question
Two long, straight wires are parallel and 10 cm apart. One carries a current of 2.0 A, the other a current of 5.0 A. What is the magnitude and direction of the force per unit length exerted by the first wire on the second wire if the currents flow in the same direction?

Answer:
Explanation:
We are given that
Distance between wires,d=10 cm=
We have to find the magnitude and direction of the force per unit length exerted by the first wire on the second wire if the currents flow in the same direction.
We know that magnetic force per unit length
Where
Using the formula
When the wires carrying current in same direction then the force between the wires attract to each other.
