An electron is projected along the axis of circular conductor carrying current I. Electron will experience
no force.
a force along the axis.
a force at angle $30^{\circ}$ with the axis.
a force perpendicular to axis.
Solution
The magnetic force experienced by the electron, $\mathrm{F}=\mathrm{qvB} \sin \theta$
As electron is projected along the axis, $\theta=0$ $\therefore \quad \mathrm{F}=0$
