Calculating E for symmetric charge distributions Calculating E for symmetric charge distributions 1) Use symmetry to sketch the behaviour of E (possible only for very symmetric distributions) 1) Pick an imaginary “Gaussian surface” S 1) Calculate the flux through S, in terms of an unknown | E | 2) Calculate the charge enclosed by S from geometry 3) Relate 3) and 4) by Gauss’s Law, solve for | E |
