Two long current carrying conductors are placed parallel to each other at a distance of $\displaystyle 8$ cm between them. The magnitude of magnetic field produced at mid-point between the two conductors due to current flowing in them is $\displaystyle 300 \mu T$. The equal current flowing in the two conductors is :
Official answer
(2)
30A in the opposite direction.
