NAME ______________________________ PART A . (40%) Each question is worth 5%. In the space provided, to the left of the question number, write the letter corresponding to the best answer to the question. ___ 1. A positive charge + Q is placed at the center of a hollow conducting sphere of inner radius R 1 , and an outer radius R 2 , as shown. The sphere was uncharged when + Q was placed at its center. The integral A d E is carried out over a spherical Gaussian surface, concentric with the hollow sphere, of radius greater than R 1 and less than R 2 . For the surface described, the result of the integration is: A d E = A. + Q/ B. Q/ C. 0 D. +2 Q/ E. 2 Q/ ___ 2. A parallel plate capacitor consists of two circular plates, each of radius R , separated by a distance d . If the radius of each plate is doubled, and the separation is not changed, the capacitance of the capacitor is: A. halved. B. unchanged. C. doubled. D. tripled. E. quadrupled. ___ 3. When an electric current flows in a metal wire, the direction of the electric field in the wire is: A. in the same direction as the current B. opposite to the direction of the current C. in circles around the current, as described by the right hand rule...
