    Answer: C = 1.319*10^-11 F

    Explanation: The formulae that relates the capacitance of a capacitor to the area of the plates, distance between the plates and dielectric constant is given as

    C = kε0A/d

    Where C = capacitance of plates = ?

    k = dielectric constant = 2.0

    Area of plates = 16.4cm² = 0.00164 m²

    d = distance between plates = 2.2 mm = 0.0022m

    By substituting the parameters, we have that

    C = 2 * 8.85*10 ^-12 * 0.00164 / 0.0022

    C = 0.029028 * 10^-12 / 0.0022

    C = 13.19 * 10^-12

    C = 1.319*10^-11 F
