This is College Physics Answers with Shaun Dychko. Two parallel conducting plates have an electric field between them of 4.50 times 10 to the 3 volts per meter and a potential difference of 15.0 kilovolts, which is 15.0 times 10 to the 3 volts. Now electric field between two conducting parallel plates is the potential difference divided by the distance by which they are separated and we can solve for this separation d by multiplying both sides by d over E and so the separation is voltage divided by electric field and this works out to 3.33 meters.
