Two metal plates are positioned horizontally and parallel to each other, $5.0\,\text{cm}$ apart. The plates have potentials of $+100\,\text{V}$ and $+20\,\text{V}$. What force acts on an electron within the electric field between the plates?
- A$2.6 \times 10^{-18}\,\text{N}$
- B$3.8 \times 10^{-18}\,\text{N}$
- C$2.6 \times 10^{-16}\,\text{N}$
- D$3.8 \times 10^{-16}\,\text{N}$
