Physics 2213 Homework #2 Spring 2009 Read: Chapter 21, sections 21.5, 6 Chapter 22, intro., sections 22.1 thru 22.4 Handouts: Electric Field Line Model, Gauss' Law Learning Goals: (Be sure you understand where and how each goal in each assignment applies to our homework, discussion, lecture, and lab activities.) * Distinguish between electric field lines and electric field vectors, and show how they are related. * Sketch and describe the electric field line geometry for these charge distributions: point charge (+ or -), electric dipole (+ - pair), 2 like charges (+ or -), sphere of charge, long line of charge, long cylinder of charge, flat sheet of charge. * Use symmetry properties of charge distributions to deduce the geometric properties of their electric fields. * Use Gauss' Law to determine the strengths of electric fields in charge systems of sufficiently high symmetry — spherical, cylindrical, and planar. * Use Gauss' law to locate electric charges. * Conceptually translate an equation for an electric field as a function of position into a graph (without doing detailed numerical calculations). * Determine the asymptotic limiting forms of the electric field as a function of position at small and large distances from a distribution of electric charge(s), and explain what these forms mean physically. * Show that your algebraic and numerical results have the correct units. * Show that your algebraic and numerical results are physically reasonable. For extra practice: Chap. 21: E's & P's: #21.57, 62, 90, 91, 99, 103, 107 (not quizzed)k ,, Chap. 22: Q's #Q22.1-6, 9; E's & P's #22.1, 5, 7, 8, 11, 13, 49, 63 To be prepared for Wednesday-Friday, Feb. 4-6, at your 2nd weekly recitation session: #21.59 [E-Field Lines & Particle Paths] #21.61 [Infinite Line Charge E-Field Lines] #21.89 [Finite Line of Charge] #21.96 [Charge Semicircle] #21.93
