Question no. 5.5 (a) Give brief explaination Share with your friends Share 0 Simran Deep Singh Thakral answered this Dear Student, We know that Torque on a dipole of moment M placed in a magnetic field B is given asτ=MBsinθwhere θ is the angle between M and B.For the system to be not in equilibrium,Torque should never equal to zero and for whichsinθ should not never be equal to 0. That is θ should never equal to 00 or 1800.At positions Q1 and Q2, The angle between magnetic field B due to P and moment placed M is 900.Therefore the systems PQ1 and PQ2 are not in equilibrium.Regards -1 View Full Answer
