The capacitor is disconnected from the battery, and its plates moved so the distance between them is tripled.

a. What is the potential difference measured across the plates now (as a multiple of the original potential difference)?

b. What is the potential energy stored in the capacitor now (as a multiple of the original potential energy stored)? Situation II: Instead of the above, the capacitor is left connected to the battery, and its plates moved so the distance between them is divided by 3.

c. What is the potential difference measured across the plates now (as a multiple of the original potential difference)?

d. What is the potential energy stored in the capacitor now (as a multiple of the original potential energy stored)?
