Unformatted text preview: Physics ZB-Section B Electricity and Magnetism Prof. luan K. Schuller Winter 2006 TEST 2 MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Name 1) A spherical object with a 2.0—m radius has a charge spread throughout it with a uniform charge density, p. If the electric field strength 3.6 m from the center of the sphere is 1.8 x 1012 N / C, what is the charge densitj of the sphere? A) 78 cm3 B) 1.8C/m3 C) 3.6C/m3 D) 5.7 C/m3 2) A constant electric ﬁeld is given by E = 2.0 9 — 4.0 jAN/ C. What orientation should the base of a 3.0 m X 5.0 m flat surface be given to minimize the ﬂux, if the height is vertical? Give your answer with a non—negative x component. A) 0 9+ 0 f." B) 4.9 9+ 1.3 _]A C) 1.3 9+ 0.67 JA D) 2.0 {‘— 4.0 ]A 3) A thin ring of radius 10 mm carries a charge of 4.0 nC. What is the approximate field strength at a point 12.0 m from the center of the ring? (The value of k is 9.0 x 109 N-m2 / C2.) A) 0.25 N/C B) 0.028 N/C C) 0.021 N/C D) 6.8 N/C 4) Four dipoles, each consisting of two charges 15.0 MC, are located in the xy—plane 1.0 mm from the origin, as shown. What is the ﬂux through the sphere? A) 5.6 x 105 N-m2/C B) 2.3 x 106 N-mZ/ C C) 4.5 x 106 N-m2/ C D) 0 N-m2 / C Code Number Version A Two hollow conducting spheres have a common center 0. The dimensions of the spheres are as shown. A charge of -100 nC is placed on the inner conductor and a charge of +60 nC is placed on the outer conductor. The inner and outer surfaces of the spheres are respectively denoted by A, B, C, and D, as shown. 5) In Figure 2, the charges on surfaces C and D respectively, in nC, are closest to: A) +100 and +60 B) +60 and 0 C) +100 and -40 D) +60 and —40 E) 0 and +60 6) When there is a net static charge present on a perfect conductor, and no other charges are present A) the charge will be uniformly distributed over the outside of the conductor (i.e., the Surface charge density will be constant). B) the electric field inside the conductor need not be zero if the conductor is hollow. C) every point throughout the entire conductor will be at zero potential. A D) every point throughout the entire conductor will be at a constant potential, but not necessarily at zero potential. E) the surface charge density will be greatest where the conductor is ﬂat and smallest where there are sharp protuberances or points. A-Z Thvfi m H szl‘ons o§ m Mr (mmcm). Queswn A1 (EH .
