A wire X of length 50cm carrying a current of 2A is placed parallel to a long wire Y of length 5m. The wire Y current of 3A. The distance between two wires is 5cm and currents flow in the same direction. The force acting on the wire Y is

 

Correct Option - 1


Detailed Solution:

F_x-y = $\frac{{\mu }_0{i}_1{i}_2}{2\pi r}\times \left(.5\right)$

$=\frac{2\times 10^{-7}\times 6\times 0.5}{0.05}$

$=\frac{6}{5}\times 10^{-5}N=1.2\times 10^{-5}$

Force on Y = 1.2 × 105N towards ‘x’
