    The space between the plates of a parallel plate capacitor is filled with a 'dielectric' whose 'dielectric constant' varies with distance as per the relation:

    $K(x) = K_0 + \lambda x$ ( $\lambda  =$ constant)

    The capacitance $C,$ of the capacitor, would be related to its vacuum capacitance $C_0$ for the relation
