Two very long, straight, parallel conductors A and B carry current of 5 A and 10 A respectively and are at a distance of 10 cm from each other. The direction of current in two conductors is same. The force acting per unit length between two conductors is : ($\mu$0 = 4$\pi$ $\times$ 10$-$7 SI unit)

Question

Two very long, straight, parallel conductors A and B carry current of 5 A and 10 A respectively and are at a distance of 10 cm from each other. The direction of current in two conductors is same. The force acting per unit length between two conductors is : ($\mu$₀ = 4$\pi$ $\times$ 10^$-$7 SI unit)

1 $\times$ 10^$-$4 Nm^$-$1 and is repulsive

2 $\times$ 10^$-$4 Nm^$-$1 and is attractive

2 $\times$ 10^$-$4 Nm^$-$1 and is repulsive

1 $\times$ 10^$-$4 Nm^$-$1 and is attractive
