Two very long, straight, parallel conductors $\displaystyle A$ and $\displaystyle B$ carry current of $\displaystyle 5 A$ and $\displaystyle 10 A$ respectively and are at a distance of $\displaystyle 10$ cm from each other. The direction of current in two conductors is same. The force acting per unit length between two conductors is : $\displaystyle \left(\mu_0=4 \pi \times 10^{-7} \mathrm{SI}\right.$ unit)
