A charge of $2.6 \times 10^{-8}\,\text{C}$, which is positive, lies in a uniform electric field with field strength $300\,000\,\text{V m}^{-1}$. How much work has to be done on the charge to shift it by a distance of $4.0\,\text{mm}$ in the direction opposite to that of 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$2.0\,\text{J}$
