7-Two materials with thicknesses and dielectric constant d, = 3cm, K, = 3 and d2 = 4cm, K2 = 4 are placed between two conductive parallel plates with surface area A = 1m². Find the charge induced on the surface of the insulator with a dielectric constant, K = 9x10-12 () 3, since the potential factor V = 20V is applied to the conductor plates. E, = Nm
