A) \[\mathbf{\vec{M}\times \vec{B}}\]
B) \[\mathbf{\vec{M}\times \vec{B}}\]
C) \[\frac{1}{2}\mathbf{\vec{M}\times \vec{B}}\]
D) \[\mathbf{\vec{M}}+\mathbf{\vec{B}}\]
Correct Answer: A
Solution :
Torque acting on the magnet is given by \[\overrightarrow{\tau }=\overrightarrow{M}\times \overrightarrow{B}\] Here:\[\overrightarrow{M}=\]magnetic moment, \[\overrightarrow{B}=\]magnetic field.You need to login to perform this action.
