A potential difference of $1000\,\text{V}$ is applied across two parallel metal plates that are separated by a distance of $2\,\text{mm}$. What is the electric field strength in the region between the plates?
- A$500\,\text{V m}^{-1}$
- B$50\,000\,\text{V m}^{-1}$
- C$50\,000\,\text{N C}^{-1}$
- D$500\,000\,\text{N C}^{-1}$
