A ceramic capacitor has a value of C=10,000 pF.  The capacitor consists of a dielectric disc between two paralell metal disc plates. The dielectric disc has a relative permittivity of 40. The diameter of the disc plates is 1 cm. The voltage across the plates is 100 V. Find the electric flux density D in the dielectric in milli Coulombs per square meter. Round off your answer to one decimal.
