Two parallel-plate capacitors are identical except that capacitor 1 has vacuum between the plates and capacitor 2 has a

dielectric slab of dielectric constant filling the space between the plates. Each capacitor is isolated (that is, not connected

to a battery), and they store equal quantities of charge.

Part A

Compare the two capacitors based on the capacitance.
