Two 2.0 cm × 2.0 cm metal electrodes are spaced 1.0 mm apart and connected by wires to the terminals of a 9.0 V battery.
a. What are the charge on each electrode and the potential difference between them?
The wires are disconnected, and insulated handles are used to pull the plates apart to a new spacing of 2.0 mm.
