PPT-Electrostatics

Essential Knowledge 1B2 There are only two kinds of electric charge Neutral objects or systems contain equal quantities of positive and negative charge with the exception of some fundamental particles that have no electric charge. 1 Electric and 64257elds 1 111 Electrostatic Force 1 112 Uniform electric 64257elds In an equilibrium situation there cannot be an electric field inside a conductor as this would cause charges electrons or ions to move around Charge density inside a conductor is zero This follows from Gausss law As the charge density This does no 2007–2008 Workshop Materials Special Focus: Electrostatics 3 A Note from the Editor Peggy Bertrand Oak Ridge High School Oak Ridge, TN One of the most di cult areas of physics to learn, and Lesson 3:.
