\textbf{179-} Between two parallel plates that are $2\,\text{cm}$ apart, we have created an electric potential difference of $500\,\text{V}$. If an alpha particle is placed between these two plates, how many newtons of electric force will act on it?
$(e = 1.6 \times 10^{-19}\,\text{C})$
(1) $8 \times 10^{-15}$ \quad (2) $8 \times 10^{-15}$ \quad (3) $4 \times 10^{-15}$ \quad (4) $4 \times 10^{-15}$
