Q. No.Two very long, straight, parallel conductor \(\mathrm{A}\) and \(\mathrm{B}\) carry current of \(5~\text{A}\) and \(10~\text{A}\) respectively and are at a distance of \(10~\mathrm{cm}\) from each other. The direction of the current in the two conductors is the same. The force acting per unit length between two conductors is:
(\(\mu_0=4\pi \times 10^{-7}\) SI unit)
(\(\mu_0=4\pi \times 10^{-7}\) SI unit)
| 1. | \(2\times10^{-4}~\text{Nm}^{-1}\) and is attractive |
| 2. | \(2\times10^{-4}~\text{Nm}^{-1}\) and is repulsive |
| 3. | \(1\times10^{-4}~\text{Nm}^{-1}\) and is attractive |
| 4. | \(1\times10^{-4}~\text{Nm}^{-1}\) and is repulsive |
