Two long parallel wires X and Y carry currents 3A and 5A each. if the force experienced by unit length is 5 x 10^-5N. the force per unit length experienced by wire Y is

3 x 10^-5

3 x 10^-6

5 x 10⁵

5 x 10^-5

Correct answer is D

since the wires are parallel to each other, the forces which they exert on each other are equal and opposite, since they must agree with newton's law of action an reaction. Hence the force exerted by the wire is equally
5 x 10^-5
