In a calculator’s liquid crystal display, the two conducting layers are $8\,\mu\text{m}$ apart. When the calculator is switched on, a $1.5\,\text{V}$ cell is connected across the conducting layers. What is the electric field strength between the layers?
- A$1.2 \times 10^{5}\,\text{V m}^{-1}$
- B$0.19\,\text{V m}^{-1}$
- C$12\,\text{V m}^{-1}$
- D$1.9 \times 10^{5}\,\text{V m}^{-1}$
