Two 13.0 cm -diameter electrodes 0.53 cm apart form a parallel-plate capacitor. The electrodes are attached by metal wires to the terminals of a 13 V battery. After a long time, the capacitor is disconnected from the battery but is not discharged.
Part A: What is the charge on each electrode right after the battery is disconnected?
Part B: What is the electric field strength inside the capacitor right after the battery is disconnected?
Part C: What is the potential difference between the electrodes right after the battery is disconnected?
