Questions 2-3
A capacitor is made by two flat plates, each with area A, separated by a distance d and thus
has capacitance Co= coA/d Then a slab having thickness a = 3d/4 and the same shape and
size as the plates is inserted between them, parallel to the plates and not touching either plate
as shown in the Figure.
