A parallel plate capacitor is used in a series RLC circuit along with a 0.650-H inductor. When the space between the plates is filled with a dielectric with κ = 5.57, the resonant frequency is 220 Hz. Now the dielectric is removed, leaving air between the capacitor plates. What is the new resonant frequency?
