A constant current `I` is flowing through a circular coil placed in uniform magnetic field `vecB` as shown. Then: A. The loop is in stable equilibriumB. The loop is in unstable equilibriumC. The torque acting on the loop is maximumD. The torque acting on the loop is `(1)/(sqrt(2))` times the maximum torque |

Answer» Correct Answer - C Torque acting on the loop is `tau=MxxB=Mbsintheta` Where `theta=` angle between `M` and `B` In the figure shown `theta=90^(@)` because `B` is in place of loop. Or `tau=MB=`maximum torque Hence, (c) is correct and choice (d) is wrong. Since, torque is acting on the loop so loop is not in equilibrium. Hence, choices (a) and (b) are wrong. |
