Your Name Recitation Instructor's Name: Recitation Section #: Physics 213 February 28, 2008 Prelim Exam #1 7:30 - 9 PM PLEASE BE SURE THIS PACKET HAS 12 PAGES ! ( This includes the cover sheet.) This packet contains 5 Short Answer Questions , 4 Problems , 1 page of scratch paper, and a page of Possibly Useful Information . Write your answers ON THESE QUESTION SHEETS in the spaces provided. For Short Answer Questions #1-5, ONLY ANSWERS WILL BE GRADED, unless calculations or constructions are explicitly requested. For Problems #6-9, where algebra or computations are required, BE SURE YOUR METHOD OF SOLUTION IS CLEAR, and SHOW ALL YOUR WORK in the spaces provided. If you need more space, use the backs of the question sheets and indicate the whereabouts of your work for each question. ANSWERS WITHOUT WORK will NOT receive credit (except for short answer questions). WORK ON SCRATCH PAPER WILL NOT BE GRADED. Point values for questions are given by each problem and below. BUDGET YOUR TIME. Don't spend too much time on any one question or part of a question. Answer those questions you can do easily first, and then return to the more difficult ones. It is valuable use of your time to READ THE ENTIRE EXAM before starting to work on it. This is a CLOSED BOOK and CLOSED NOTES exam. You may NOT use any other references or personal assistance.

2 I. SHORT ANSWER [43 points] Write your answer letters in the spaces provided. 1. [12 points] True OR False (Please write T or F in the spaces.) (a) The maximum magnitude of electric charge that the 0.25 m diameter spherical metal dome of a Van de Graaff generator like the one used in lecture can hold before sparking is typically around a coulomb. (b) When using Gauss' Law to find the electric field due to a distribution of electric charge, the electric field written in the electric flux integral must be the electric field due to only the charge enclosed by the Gaussian bubble. (c) The electric field is zero throughout the interior of a thin hollow ellipsoidal shell of electric charge that has uniform surface charge density. (d) A superconductor is a material whose electrical resistance decreases to exactly zero when it is cooled below a certain critical temperature.
