Calculating ~ E from Gauss’ Law: Charged Plane Sheet Consider a uniformly charged plane sheet. Charge per unit area on sheet: σ (here assumed positive). Use Gaussian cylinder with cross-sectional area A placed as shown. Electric flux through Gaussian surface: Φ E = I ~ E · d ~ A = 2 EA. Net charge charge inside Gaussian surface:
