Here's the question:(adsbygoogle = window.adsbygoogle || []).push({});

A square plate of copper with 50.6 cm sides has no net charge and is placed in a region of uniform electric field of 80.9 kN/C directed perpendicularly to the plate.

a. Calculate the charge density of each face of the plate.

b. Calculate the total charge on each face.

I know I can find the total charge with density*area, and I know that density = Q/A, I just don't know how to convert the field into a charge, and I'm not even sure if that's what I'm supposed to do. Any help would be great.

Thanks a lot
