Two parallel plates have equal and opposite charges. When the space between the plates is evacuated, the electric field is E = 5.40 x 105 V/m. When the space is filled with a dielectric, the electric field is E = 3.60 x 105 V/m. What is the charge density on each surface of the dielectric? (0 = 8.85 x 10 -12 F/m)
