question 27

Short Answer

Two extremely large nonconducting horizontal sheets each carry uniform charge density on the surfaces facing each other. The upper sheet carries +5.00 µC/m². The electric field midway between the sheets is 4.25 × 10⁵ N/C pointing downward. What is the surface charge density on the lower sheet? (ε0 = 8.85 × 10^-12 C²/N ∙ m²)
