A parallel plate capacitor has plates of area A separated by distance ‘d’ between them. It is filled with a dielectric which has dielectric constant that varies as `K (y) = k _(0) (1+ alpha y)` where ‘y’ is the vertical distance measured from base of the plates. The total capacitance of the system is best given by: `(K _(0) `is constant)
