(D) The electric field $E$ between the parallel plates is given by $E = \frac{V}{d}$.Given, $V = 10^4 \,V$ and $d = 0.5 \,cm = 0.5 \times 10^{-2} \,m$.Therefore, $E = \frac{10^4}{0.5 \times 10^{-2}} = 2 \times 10^6 \,V/m$.The force $F$ on an electron of charge $e = 1.6 \times 10^{-19} \,C$ is given by $F = eE$.$F = (1.6 \times 10^{-19} \,C) \times (2 \times 10^6 \,V/m) = 3.2 \times 10^{-13} \,N$.
