Week 7: Applying Gauss' Law: Cylindrical Symmetry, Applying Gauss' Law: Planar Symmetry, Applying Gauss' Law: Spherical Symmetry, Check points, Questions and Problems

In this class we will practice calculating electric fields using Gauss's law by doing problem solving #3. Remember that the idea behind Gauss’s law is that, pictorially, electric fields flow out of and into charges. If you surround some region of space with a closed surface (think bag), then observing how much field “flows” into or out of that surface tells you how much charge is enclosed by the bag. For example, if you surround a positive charge with a surface then you will see a net flow outwards, whereas if you surround a negative charge with a surface you will see a net flow inwards.
