An electron is projected along the axis of circular conductor carrying current ' $I$ ' The electron will experience
a force perpendicular to axis
a force along the axis
a force at angle $30^{\circ}$ with the axis
no force
Solution
The direction of the magnetic field will be along the axis. The angle between the velocity and the magnetic field will be $0^{\circ}$ or $180^{\circ}$. The force is given by $\mathrm{F}=\mathrm{qvB} \sin \theta$
If $\theta=0^{\circ}$ or $180^{\circ}, \mathrm{F}=0$
