Physics - Magnetism Question with Solution | TestHub

An electron with kinetic energy $5\mathrm{eV}$ enters a region of uniform magnetic field of 3 $\mu \mathrm{T}$ perpendicular to its direction. An electric field $\mathrm{E}$ is applied perpendicular to the direction of velocity and magnetic field. The value of $E$, so that electron moves along the same path, is _______ ${\mathrm{NC}}^{-1}$. $($ Given, mass of electron $=9\times 10^{-31}\mathrm{kg}$, electric charge $=1.6\times 10^{-19}\mathrm{C})$
