Question

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

A
$1 \times 10^6 \, \text{m/s}$
B
$0$
C
$16 \times 10^6 \, \text{m/s}$
D
$16 \times 10^4 \, \text{m/s}$
