A charge of $2.6 \times 10^{-8}\,\text{C}$, which is positive, is in an electric field with a constant field strength of $300\,000\,\text{V m}^{-1}$. What amount of work is required to move the charge a distance of $4.0\,\text{mm}$ in the direction opposite to the field?
- A$3.1 \times 10^{-5}\,\text{J}$
- B$2.0 \times 10^{-3}\,\text{J}$
- C$3.1 \times 10^{-2}\,\text{J}$
- D$2.0\,\text{J}$
