Question

Two identical long conducting wires $AOB$ and $COD$ are placed at right angle to each other, with one above other such that $O$ is their common point for the two. The wires carry $I$₁ and $I$₂ currents, respectively. Point $P$ is lying at distance f from $O$ along a direction perpendicular to the plane containing the wires. The magnetic field at the point $P$ will be

${{{\mu _0}} \over {2\pi d}}\left( {{{{I_1}} \over {{I_2}}}} \right)$

${{{\mu _0}} \over {2\pi d}}\left( {{I_1} + {I_2}} \right)$

${{{\mu _0}} \over {2\pi d}}\left( {I_1^2 - I_2^2} \right)$

${{{\mu _0}} \over {2\pi d}}{\left( {I_1^2 + I_2^2} \right)^{1/2}}$
