Phys2426.Qz2.Chap22(Gauss's Law) Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) 1) A flat disk 1.0 m in diameter is oriented so that the plane of the disk makes an angle of Δ /6 radians with a uniform electric field. If the field strength is 491.0 N/C, find the electric flux through the surface. A) 430 N · m 2 /C B) 110 Δ N · m 2 /C C) 61 Δ N · m 2 /C D) 1700/ Δ N · m 2 /C 2) 2) A small particle with a mass of 2.0 kg carrying a charge of 2.0 nC is at the surface of a charged spherical conductor of radius 1.0 mm. If the surface charge density is 8.0 C/m 2 , find the acceleration of the particle. (The constant Ή o is 8.85 × 10 - 12 C 2 /N · m 2 . The value of k is 9.0 × 10 9 N · m 2 /C 2 .) A) ^ 900 r m/s 2 B) ^ 8000 r m/s 2 C) ^ 0.0080 r m/s 2 D) ^ 8.0 r m/s 2 3) 3) A hollow spherical conductor of inner radius 2.0 cm has a 2.0 C point charge at its center. Find the surface charge density at the outer surface of the sphere. The thickness of the sphere is 1.0 mm.
