An interface between two dielectrics coincides with the x=0 plane as shown below. The electric

field intensity in medium (1) is E1 = 100ax + 300ay – 50az [V/m]. A surface charge density

ρs = 5×10-10 C/m2 exists on the interface:

(a) Calculate the electric field intensity in medium (2).

(b) Calculate the electric flux density in medium (2).
