The figure below shows two horizontal parallel metal plates with a separation distance d between them. Determine the electric field vectors at points A, B and C if connecting these plates to a battery results in one plate acquiring a uniform charge density of σ₁ = +2σ₀ and the other plate obtaining a uniform charge density of σ₂ = -σ₀.

• A. $\overrightarrow{E_{A}}$ = $\frac{\sigma_0}{2\varepsilon_0}$ ĵ , $\overrightarrow{E_{B}}$ = -$\frac{3\sigma_0}{2\varepsilon_0}$ ĵ , $\overrightarrow{E_{C}}$ = -$\frac{\sigma_0}{2\varepsilon_0}$ ĵ
• B. $\overrightarrow{E_{A}}$ = $\frac{\sigma_0}{2\varepsilon_0}$ ĵ , $\overrightarrow{E_{B}}$ = $\frac{3\sigma_0}{2\varepsilon_0}$ ĵ , $\overrightarrow{E_{C}}$ = $\frac{\sigma_0}{2\varepsilon_0}$ ĵ
• C. $\overrightarrow{E_{A}}$ = -$\frac{3\sigma_0}{2\varepsilon_0}$ ĵ , $\overrightarrow{E_{B}}$ = -$\frac{\sigma_0}{2\varepsilon_0}$ ĵ , $\overrightarrow{E_{C}}$ = -$\frac{\sigma_0}{2\varepsilon_0}$ ĵ
• D. $\overrightarrow{E_{A}}$ = -$\frac{\sigma_0}{2\varepsilon_0}$ ĵ , $\overrightarrow{E_{B}}$ = -$\frac{3\sigma_0}{2\varepsilon_0}$ ĵ , $\overrightarrow{E_{C}}$ = -$\frac{\sigma_0}{2\varepsilon_0}$ ĵ
