August 12, 2010 University Physics, Chapter 22 69 Planar Symmetry (2) ! To calculate the electric field using Gauss’ Law, we assume a Gaussian surface in the form of a right cylinder with cross sectional area A and height 2r, chosen to cut through the plane perpendicularly. ! Because the electric field is perpendicular to the plane
