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?

So the problem ask to find the charge that is present at the top plate of the capacitor where as the two plates has an area of 3490cm^2. Base on that data and the connection of the circuits or plates, i came up with an answer of 8*10^-7 coulomb. I hope you are satisfied with my answer and feel free to ask for more
