Electrostatics

A charge \(17.7 \times 10^{-4} \mathrm{C}\) is distributed uniformly over a large sheet of area \(200 \mathrm{~m}^2\). The electric field intensity at a distance \(20 \mathrm{~cm}\) from it in air will be \(\left[\varepsilon_0=8.85 \times 10^{-12} \mathrm{C}^2 / \mathrm{Nm}^2\right]\)
