In the given set-up, plot the E fields inside both dielectrics if a. No charge is present in the interface. b. Charge is present in the interface (p, is nonzero of your choice) c. Plot the magnitude of E fields (E) at each points in question 1(a). (Change the values of dielectric constants in both layers and plot E. Explain your observation.) (0, 0) & = 3 & = 6 E = -2xx - y X
