+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.I know answer comes with MxB but still
In M×B you assumed theta to be 90 right? So how are the forces in same plane
It will rotate about horizontal axis
Magnetic moment and magnetic field, how can the angle btw them be 90° ?
It's either 0 or 180
Wait....
Why did i take it 90°
......
Im even more confused now
Why did 90 give the correct ans
Answer should be D ideally question is ambiguos
we good?
