7.) Why does the electric field due to a dipole decrease more rapidly with increasing distance than that for a single charge? a) The total charge of the dipole is neutral (zero). b) Because there are two charges in the dipole, the electric field has one-half the field strength of a single charge. c) Any given point is closer to one of the charges of the dipole than to the other. d) The two charges in the dipole are separated by some distance. 8.) Complete the following sentence: The normal to the surface of a spherical mirror is a) always parallel to the central axis. b) always perpendicular to the central axis. c) parallel to the surface of the mirror. d) a line drawn from the center of curvature to the surface of the mirror. 9.) Which of the following parameters is not needed to use the mirror equation to solve for an unknown parameter? a) the object distance b) the height of the object c) focal length of the mirror d) the image distance
