Question A capacitor with parallel plates, of area A and separation 2a, is connected to a potential difference AV. Then a conductive metal plate of area is introduced A/2 and thickness a up to the middle of the capacitor (red in the figure). Finally it is introduced an insulating material of dielectric constant k in the second half (blue in the figure), with equal area and thickness as conductive material. Find The capacity and energy accumulated when the capacitor is with the conductor. 

What do you mean by c3 and c2? Are the capacitor with conductor and the other with air? What area and distance is used to calculate the capacitor with air and to calculate the one with the conductor?
