Question: 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 (kappa)

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 $\kappa$ filling the space between the plates. Each capacitor is isolated (that is, not connected to a battery), and they store equal quantities of charge. Compare the two based on

(a) capacitance,

(b) potential difference between the plates,

(c) energy stored,

$(d)$ electric field magnitude between the plates, and

(e) energy density.
