2. Using separated electric charge: Two metal Leyden jar cylinders are separated by an insulating plastic cup. The outer metal cylinder is connected to a ground wire. The inner metal cylinder is given a negative charge. a) Is the net charge on the outer metal cylinder positive or negative? b) Why does some negative charge from the outer cylinder ow down the ground wire? c) A small bulb is connected between the inner and outer metal cylinders, causing the bulb to light. Why does some negative charge from the inner cylinder ow through the bulb? d) A voltmeter is connected between the inner and outer metal cylinders. Does the voltage measured by the voltmeter increase or decrease when the inner cylinder is raised? Why does this happen? ol1tI1E
