An electron is projected along the axis of circular conductor carrying current 1 . Electron will experience
a force at an angle of $30^{\circ}$ with the axis.
no force.
a force along the axis.
a force perpendicular to the axis.
Solution
The velocity of the electron is parallel or antiparallel to the magnetic field.
$F=e v B \sin \theta$
$\theta=0^{\circ}$ or $180^{\circ}$
$\therefore \mathrm{F}=0$
