Physics 51 Proficiency Test 2(sample) (Time: 10 minutes) 25 points By Todd Sauke Name ___________ KEY ________ Section # __ KEY ___ Two concentric, hollow, spherical conducting shells are placed as shown in the figure at right. A total charge of –200 nano-Coulombs (nC = 10 -9 C) is placed on the outer conductor, a total charge of +500 nC is placed on the inner conductor, and a charge Q = -400 nC is placed at the very center. First, what is the magnitude of the E-field (at equilibrium)on the interior of each conductor? _________ 0 ___________ N/C
