Consider first a single infinite conducting plate. In order to apply Gauss''s law with one end of a cylinder inside of the conductor, you must assume that the conductor has some finite thickness.
What happens to the charge on the capacitor immediately after the switch is thrown? A. The electrons on the negative plate of the capacitor are held inside the capacitor by the positive charge on the other plate. B. Only the surface charge is held in the capacitor; the charge inside the metal plates flows through the resistor. C.
