A current carrying circular loop of radius 2 cm with unit normal \(\hat{n}=\frac{\hat{k}+\hat{i}}{\sqrt{2}}\) is placed in a magnetic field, \(\vec{B}={B}_{o}(3\hat{i}+2\hat{k})\). If \({B}_{o}=4\times {10}^{-3}T\) and current \(I=100\sqrt{2}A\), the torque experienced by the loop is ________ Wb.A. \((\pi =3.14)\)
