Two parallel plates have equal and opposite charges. When the space between the plates is evacuated, the electric field is E= 3.50×105 V/m. When the space is filled with dielectric, the electric field is E= 2.30×105 V/m.1.What is the charge density on each surface of the dielectric? (|Sigma i | = ? C/m^2)2.What is the dielectric constant?
