Two parallel plates, each having area a = 3490cm2 are connected to the terminals of a battery of voltage vb = 6 v as shown. the plates are separated by a distance d = 0.36cm. you may assume (contrary to the drawing) that the separation between the plates is small compared with either linear dimension of the plate. a dielectric having dielectric constant κ = 3.6 is now inserted in between the plates of the capacitor as shown. the dielectric has area a = 3490 cm2 and thickness equal to half of the separation (= 0.18 cm) . what is the charge on the top plate of this capacitor?
