A point charge Q [C] is located at a point in space. The charge is surrounded by two spherical layers of materials as shown below. Both materials have permittivity's different than free space (2>&1), as indicated: + E² to J/m³ D (a) Calculate the electric flux density and field intensity everywhere in space. (b) Calculate the potential everywhere in space. (c) Plot the electric field intensity and electric flux density everywhere in space. (d) Calculate the energy stored in region R2. (e) determine the charge distribution at R3. E everywhere. casel-D Point charge. Ф 4776052 a = E.Eds = Qenclosed.
