5) Point charge in a dielectric medium: (10 pts) A point charge q is fixed inside a sheet of glass with a relative permittivity of 5. By what factor does the strength of the electric field inside the dielectric differ from its magnitude in vacuum? Given your result, is the electric field due to the point-charge stronger, weaker, or the same in magnitude to that of a point charge in vacuum? 4 = 5
