//Problem 6.04: Two parallel rectangular plates measuring 20 cm by 40 cm carry an electric charge of 0.2 μC. Calculate the electric flux density. If the plates are spaced 5 mm apart and the voltage between them is 0.25 kV determine the electric field strength. //initializing the variables: Q = 0.2E-6; // in Coulomb A = 800E-4; // in m2 d = 0.005; // in m V = 250; // in Volts //calculation: D = Q/A E = V/d printf("\n\nResult\n\n") printf("\n (a)Electric flux density D %.2E C/m2",D) printf("\n (b)Electric field strength E %.2E V/m\n",E)
