|
False

|
Either A or B

|
None of the above

Explanation:
Detailed explanation-1: -The larger the dielectric constant, the more charge can be stored. Completely filling the space between capacitor plates with a dielectric, increases the capacitance by a factor of the dielectric constant: C = KCo, where Co is the capacitance with no slab between the plates.
Detailed explanation-2: -Correct answer: When a dielectric is added to a capacitor, the capacitance increases. In our problem, it says the system is charged and isolated, which means no charge will escape the system. Therefore the charge on the plates will stay the same.
