A capacitor has rectangular plates of length a and width b. The top plate is inclined at a small angle as shown in Figure. The plate separation varies from d = y0 at the left to d = 2y0 at the right, where y0 is much less than a or b. Calculate the capacitance using strips of width dx and length b to approximate differential capacitors of area b dx and separation d = y0 + (y0/a)x that are connected inparallel.
