PHYSICS 200 CLASS 5 SPRING 2004(22 January 04)ASSIGNMENT: HRW, Chapter 24.CONCEPTS: 1. Gauss's law, and why it is equivalent to Coulomb’s law.2. "Gaussian surfaces." As you think about this idea, ask yourself therelated question of how one measures the area of an irregularly shapedsurface.3. idea of "electrostatic equilibrium"--charges in equilibrium don't movearound4. The electric field inside a conductor must be zero. Be sure youunderstand why.5. In electrostatics, the charge on a conductor must reside entirely on theoutside surface. Be sure you can use Gauss’s law to explain why.6. Use Gauss's Law to calculate electric fields for "symmetric"geometries.RECOMMENDED QUESTIONS AND PROBLEMS: Be sure you understand thesymmetry arguments used to apply Gauss’s law to plane, cylindrical, and sphericalgeometries, and see if you can do some of the problems for sections 7–9. I will assignmore problems along these lines next time.-----------------------------------------------------------------TURN IN: Chapter 24, Question G-25; Problems 7, 9, 15, 19, 25.For the question, remember that “G-” refers to the green supplementaryproblem book. As with all questions, be sure to explain your reasoningcarefully.NOTES AND ANNOUNCEMENTS1. The second laboratory meets days 4, 5 and 6, Friday, Monday and Tuesday 23, 26and 27 January. We will do Experiment 2, Electrical Circuits.2. First exam: We will spend Monday on Chapter 24, and then move on to Chapter 25.That chapter should take us about three days. This schedule should put the first examsometime the week of 2 February.
