PHY 2049 Study Guide - Midterm Guide: Gaussian Surface, Electric Flux, Electric Field
Document Summary
Study sections 22. 1 through 22. 4 in the text book. Memorize the definition of flux and memorize gauss"s law. If the electric flux through a closed surface is zero, the electric field at points on that surface must be zero. False because the electric flux in a closed surface is zero if there are not electric charges enclosed on it. Consider a spherical gaussian surface of radius r centered at the origin. A charge q is placed inside the sphere. To maximize the magnitude of the flux of the electric field through the gaussian surface, the charge should be located. The charge can be located anywhere, since flux does not depend on the position of the charge as long as it is inside the sphere. Assume that the presence of the disk does not interfere with the electric field. Express your answer in terms of e, a, and .
