Two infinite long wires each carrying a current $10 \mathrm{~A}$ are bend to form a right angle as shown in the figure. Then the magnetic induction at ' $\mathrm{O}$ ' is $\left[\mu_0=4 \pi \times 10^{-7} \mathrm{Hm}^{-1}\right]$
  1. $\begin{aligned} & 1 \times 10^{-3} \mathrm{~T}\end{aligned}$
  2. $\begin{aligned}& 1 \times 10^{-4} \mathrm{~T} \end{aligned}$
  3. $\begin{aligned} & 3 \times 10^{-4} \mathrm{~T} \end{aligned}$
  4. $\begin{aligned} &0\end{aligned}$
