Physics - Magnetism Question with Solution | TestHub

A charged particle of mass$\mathrm{m}$and charge$\mathrm{q}$is projected into a uniform magnetic field of induction$\mathrm{B}$with speed$\mathrm{v}$which is perpendicular to$\mathrm{B}$. The width of the magnetic field is$\mathrm{d}$. The impulse imparted to the particle by the field is

$\left(\mathrm{d}\mathrm{ }<<\mathrm{ }\frac{\mathrm{m}\mathrm{v}}{\mathrm{q}\mathrm{B}}\right)$
