A potential difference of $12\,\text{kV}$ is applied across two parallel plates separated by a gap of $25\,\text{mm}$. What force acts on an electron located in the uniform electric field between the plates?
- A$4.8 \times 10^{-20}\,\text{N}$
- B$7.7 \times 10^{-20}\,\text{N}$
- C$4.8 \times 10^{-17}\,\text{N}$
- D$7.7 \times 10^{-14}\,\text{N}$
