7. (a) The space between two parallel plate capacitor is filled with two dielectric materials of same dimensions. What is the resulting capacitance as a function of K₁, K₂ and the original Co when the space in between is empty? (b) What would be the resulting capacitance of the following setup then? Express your answer as a function of K₁, K₂ and the original Co when the space in between is empty?

A parallel plate capacitor has a capacitance of 5.5 µF when filled with a dielectric. The area of each plate is 2.0 m2 and the separation between the plates is 0.84E-5 m. What is the dielectric constant of the dielectric?
