3. A uniform magnetic field $\mathrm{B}=\left(3\hat{\mathrm{i}}+4\hat{\mathrm{j}}+\hat{\mathrm{k}}\right)$ exists in region of space. A semicircular wire of radius 1 m carrying current 1 A having its centre at (2. 2, 0) placed in x-y plane as shown in fig. The force on semicircular ​ wire will be.
$$\begin{gathered} \left(\mathrm{A}\right) \sqrt{2}\left(\hat{\mathrm{i}}+\hat{\mathrm{j}}+\hat{\mathrm{k}}\right) \left(\mathrm{B}\right) \sqrt{2}\left(\hat{\mathrm{i}}-\hat{\mathrm{j}}+\hat{\mathrm{k}}\right) \\ \left(\mathrm{C}\right) \sqrt{2}\left(\hat{\mathrm{i}}+\hat{\mathrm{j}}-\mathrm{k}\right) \left(\mathrm{D}\right) \sqrt{2}\left(\widehat{-\mathrm{i}}+\hat{\mathrm{j}}+\hat{\mathrm{k}}\right) \end{gathered}$$
