An electron with kinetic energy $\displaystyle 5$ eV enters a region of uniform magnetic field of $\displaystyle 3$ $\displaystyle \mu \mathrm{T}$ perpendicular to its direction. An electric field 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 $\displaystyle \_\_\_\_$ $\displaystyle \mathrm{NC}^{-1}$. (Given, mass of electron $\displaystyle =9 \times 10^{-31} \mathrm{~kg}$, electric charge $\displaystyle =1.6 \times 10^{-19} \mathrm{C}$ )
