Consider a parallel plate capacitor with plates in the shape of square and in X-Y plane. The gap between the plates is filled with dielectric material. The dielectric constant k varies with X-axis as k (x) = [1+(x/L)^\alpha] where α is a constant. Let C_d and C_a are capacitance in the presence of dielectric and air respectively. If the ratio C_d/C_a = 7/6 , then the value of α must be
