Two Very Large,flat Plates Are Parallel to Each Other

Two very large,flat plates are parallel to each other. Plate A,located at y = 1.0 cm,is along the xz-plane and carries a uniform surface charge density -1.00 μC/m². Plate B is located at y = -1.0 cm and carries a uniform surface charge density +2.00 μC/m².What is the electric field vector at the point having x,y,z coordinates (-0.50 cm,0.00 cm,0.00 cm) ? (ε₀ = 8.85 × 10^-12 C²/N • m²)

A) (+1.13 × 10⁵ N/C)
B) (-2.83 × 10⁵ N/C)
C) (+1.19 × 10⁵ N/C)
D) (+1.69 × 10⁵ N/C)
E) (-1.19 × 10⁵ N/C)
