5. A capacitor is charged by a battery. It may or may not have been removed from this battery. A dielectric is then either inserted or removed from between the plates. The capacitance increased by a factor of 5 and the charge across the plates increased by a factor of 5. a. Was the capacitor on or off the battery? Explain. b. Was the dielectric inserted or removed from between the plates? Explain.

Given a 10 pF air-filled capacitor, you are asked to convert it to a capacitor that can store up to 8.3 µJ with a maximum potential difference of 662 V. What must be the dielectric constant of the material that you should you use to fill the gap in the air capacitor if you do not allow for a margin of error? Number Units
