1. (10 points) The figure shows a capacitor of plate area A = 15.0 cm and plate separation 2d= 24 mm. The left half of the gap is filled with material of dielectric constant K1 = 21.4, K2 =15.6; the right half is filled with material of dielectric constant K3 = 41.6, K4 = 57.3. (a) What is the capacitance? (b) If a potential difference of V = 50 V is applied across the capacitor, what are the charge q and the stored energy U in the capacitor. A/2 -A/2 K1 K3 Ta 2d K KA
