    Calculate capacitance of a parallel plate but of made up o two media!?

    The parallel plate capacitor in the figure below is quarter-filled with mica (εr=6). Its remaining ¾ part is filled with air. The total area of the capacitor is 10 cm2 and the distance separating the plates is 2mm. Find the capacitance of this capacitor.
    This is the figure: http://postimg.org/image/p2hdvdvld/
    Please show steps.
    Even my teacher couldn't solve this question correctly, she says we need to have the charge.

    Hi BeeDee10! Welcome to PF! :smile:

    Hint: divide the diagram into four capacitors. :wink:
