Quiz 4 Phys. 2306 F09 CRN 94850 You may use your text book, notes, and a calculator. Consider a hollow conductor. Its outer surface is a sphere with radius, R=0.100 m, while the inner surface is irregular. In the hollow cavity and insulated from the conductor, a total charge, Q=5.00 nC, is spread about. The conductor carries a total charge, Q’= - 6.00 nC. Take the origin at the center of the sphere (which could be in the body of the conductor) and use 1 4 π± 0 = 8 . 988 × 10 9 N(m/C) 2 . 1) What is the charge in nC on the inner surface of the conductor? a) 5.00 b) -5.00 c) 1.00 d) -1.00 e)none of these Draw a gaussian surface that is everywhere in the body of the conductor. Thus every- where on this surface E = 0 and the surface can enclose no charge (from the gauss law). If you let the gaussian surface just surrround the inner surface of the conductor, in order to enclose zero charge, there must be a charge - Q = - 5 . 00 nC induced on the conductor’s inner surface, (b). 2) What is the charge in nC on the outer surface of the conductor?
