Q.A magnetic dipole in a constant m-field has:

  1. zero potential energy when the torque is maximum
    2.maximum potential energy when the torque is maximum
    3.zero potential energy when the torque is minimum
    4.minimum potential energy when the torque is maximum.
    I think option 4 is correct.

When can we get the answer key of jee mains online paper 1, 8 april 2017???


#6

Option 1st is correct, when torque is maximum, ø=π/2, so U = 0, but in option 4, it says U = minimum which is possible at ø=0, where U is -BM.
