An electron is made to enter symmetrically between two parallel and equally but oppositely charged metal plates, each of $\displaystyle 10$ cm length. The electron emerges out of the electric field region with a horizontal component of velocity $\displaystyle 10^6 \mathrm{~m} / \mathrm{s}$. If the magnitude of the electric field between the plates is $\displaystyle 9.1 \mathrm{~V} / \mathrm{cm}$, then the vertical component of velocity of electron is (mass of electron $\displaystyle =9.1 \times 10^{-31} \mathrm{~kg}$ and charge of electron $\displaystyle =1.6 \times 10^{-19} \mathrm{C}$ )
