Questions 2-3 A capacitor is made by two flat plates, each with area A, separated by a distance d and thus 不 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. ←8⇒ Ill yok 2. What is the capacitance of this arrangement, in units of Co, if the slab is made of conducting material? (a) 3/4 (b) 2 (c) 4 (d) 4/3 (e) 1/4 3. What is the capacitance of this arrangement, in units of Co, if the slab is made of dielectric material of dielectric constant K = 3? (a) 2 (b) 3 (c) 1/2 (d) 4 (e) 1/4
