Two infinitely long straight wires \(A\) and \(B\), each carrying current \(I\) are placed on \(x\) and \(y\)-axis, respectively. The current in wires \(A\) and \(B\) flow along \(-\hat{\mathbf{i}}\) and \(\hat{\mathbf{j}}\) directions respectively. The force on a charged particle having charge \(q\), moving from position, \(\mathbf{r}=d(\hat{\mathbf{i}}+\hat{\mathbf{j}})\) with velocity \(\mathbf{v}=\hat{v}\) is

1. A \(\frac{\mu_0 f v^{\prime}}{2 \pi \sigma^{\prime}} \hat{\mathbf{j}}\)
2. B \(\frac{\mu_0 f q v}{\pi \sigma^{\prime}} \hat{\mathbf{j}}\)
3. C \(\frac{\mu_0 f Q v}{\sqrt{2} \pi \phi} \hat{\mathbf{k}}\)
4. D 0
