Question: A magnet of magnetic moment $50\,\hat i\,A{\rm{ - }}{m^2}$ is placed along the x-axis in a magnetic field $\overrightarrow B = (0.5\,\hat i + 3.0\hat j)\,T.$ The torque acting on the magnet is

1) 175 $\hat k\,\,N{\rm{ - }}m$

2) 150 $\hat k\,\,N{\rm{ - }}m$

3) 75 $\hat k\,\,N{\rm{ - }}m$

4) $25\sqrt {37} \,\hat k\,\,N{\rm{ - }}m$
