Unformatted text preview: 26. According to Eq. 24-13 the electric field due to either sheet of charge with surface charge density σ is perpendicular to the plane of the sheet (pointing away from the sheet if the charge is positive) and has magnitude E = σ/2ε0 . Using the superposition principle, we conclude: (a) E = σ/ε0 , pointing up; (b) E = 0; (c) and, E = σ/ε0 , pointing down. ...
