where is the key for 8th april mains online exam uploaded?


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 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???


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.



Hey akshay correct option is1 when torque is maximum potential energy is zero
