1. The magnitude of the electric field between two plates of a parallel plate capicitor is 4.7 x 10^4 N/C, if the charge on each plate increases by a a factor of 3, what happens to the electric field? increase by a factor of 3 or 9? decrease by a factor of 3 or 9? not effected? 2. Electric field for plates = V/d 3. Thate the only equation i know and we did not learn any equation that reprensets charges on each plate so im totally confused about how to relate the question... maybe logically? Umm since the charge on each plate increases by 3 the electric field will get stronger by the same factor of 3?
