1. (5 points) The electric potential inside a charged solid spherical conductor in equilibrium a. is always zero. b. is constant and equal to its value at the surface. c. decreases from its value at the surface to a value of zero at the center. d. increases from its value at the surface to a value at the center that is a multiple of the potential at the surface. e. is equal to the charge passing through the surface per unit time divided by the resistance. 2. (6 points) A parallel plate capacitor of capacitance C 0 has plates of area A with separation d between them. When it is connected to a battery of voltage V 0 , it has a charge of magnitude Q 0 on each of its plates. While it remains connected to the battery the separation between the
