The figure shows three situations when an electron with velocity $v$ travels through a uniform magnetic field $B$ . In each case, what is the direction of magnetic force on the electron?

Options:

Answer:

Solution:

According to Fleming's Right hand Rule In (1) force is in $- z$ axis In (2) force is in - $x$ -axis In (3) force is zero because $F = q (\overline{v} \times \overline{B}) = qvB sin 180$ i.e. $F = 0$
