Extracted text: A V K1 K2 42 Two insulating materials with thicknesses and dielectric constants d1 = 3cm, K1 = 3 and d, = 4cm, K2 = 4 are placed tightly in between two conductive parallel plates with surface area A = 1m?. Since the potential difference V = 20V is applied to the conductor plates, find the induced charge on the surface of the insulator with dielectric constant K, = 3. ɛ, = 9x10-12() Nm2. a) 2.25x10-°C b) 6x10-9C c) 1.35x10-8C d) 2.88x10-8C e) 4.5x10-8C
