2. A capacitor consists of two metal plates, each 200mm by 300mm, spaced 9mm apart. The spaced between the metal plates is filled with mica 6mm thick and a layer of paper 3mm thick. The relative permittivity of the mica and paper are 9 and 6 respectively. Calculate: the i. capacitance and ii. electric field strength in each dielectric in kV/mm due to a pd of 10kV between the metal plates.
