A particle carries a charge of $+2.0\,\text{mC}$ and is located in a vertical uniform electric field. The particle experiences an upward electric force of $1.0 \times 10^{-2}\,\text{N}$. What is the electric field strength?
- A$0.20\,\text{V m}^{-1}$ downwards
- B$0.20\,\text{V m}^{-1}$ upwards
- C$5.0\,\text{V m}^{-1}$ downwards
- D$5.0\,\text{V m}^{-1}$ upwards
