A parallel plane through x = 1cm has charge density 2 = 1 / 2 . Compute the electric field in the region between the planes. Select One of the Following: (a) 3 1 2 x (b) 1 4 x (cAnswer) 3 1 4 x (d) 1 4 x (e)  3 1 4 x Solution Section 1  Draw the System 1 (a) Draw a Good Diagram: This will yield a diagram with charge labeled and divided into re gions. + + + + + + a b Gaussian Surface E I E II E III Q 1 Q 2 I II III Section 2  Compute the Field in the Outer Re gions Compute the electric field in regions I and III, the outermost regions. (a) Use a Gaussian Surface Enclosing all Charge: Use a surface, labeled a, with the left end in region I and the right end in region III , our general expression for Gauss Law for planes becomes: E I + E III = Q total A ....
