Solve the all parts of following question given below:

Question: Two 12-cm-diameter electrodes 0.54cm apart from a parallel-plate capacitor. The electrodes are attached by metal wires to the terminals of a 14V battery. What are the charge on each electrode, the electric field strength inside the capacitor, and the potential difference between the electrodes?

Part A: What are the charge on each electrode, the electric field strength inside the capacitor, and the potential difference between the electrodes while the capacitor is attached to the battery?

Part B: After insulating handles are used to pull the electrodes away from each other until they are 1.5cm apart? The electrodes remain connected to the battery during this process.

Part C: After the original electrodes (not the modified electrodes of part B) are expanded until they are 21cm in diameter while remaining connected to the battery?
