23. A parallel plate capacitor of area A, plate separation d and capacitance C is filled with three different dielectric materials having dielectric constants k1, k2 and k3 as shown. If a single dielectric material is to be used to have the same capacitance C in this capacitor then its dielectric constant k is given by parallel-plate-capacitor (A) 1/k = 1/k1 + 1/k2 + 1/(2k3) (B) 1/k = 1/(k1 + k2 ) + 1/(2k3 ) (C) k = (k1 k2)/(k1 + k2 ) + 2k3 (D) k = (k1 k3)/(k1 + k2 ) + (k2 k3)/(k2 + k2 )
