Two long and parallel straight conducting wires carrying currents of 5 A and 10 A in same direction are separated by a distance of 2cm. The force per unit length on one wire due to other is $(μ_0: 4π×10^{-7} NA^{-2})$ |
$5 × 10^{-4} N/m$; attractive force $5 × 10^{-4} N/m$; repulsive force $2.5 × 10^{-4} N/m$; attractive force $2.5 × 10^{-4} N/m$; repulsive force |
$5 × 10^{-4} N/m$; attractive force |
The correct answer is Option (1) - $5 × 10^{-4} N/m$; attractive force |
