This question, I didn't get either, just because I was trying to solve for magnitude, but in reality I solved for something that doesn't even exist. Anyways, the answer to this question is suppose to 0.62 kN/C, which I tried to work backwards and such, but had no luck in getting it correctly, or atleast to have the variables line up.
The question is...
---------------------------
Charge of a uniform density (8.0 nC/m^2) is distributed over the entire xy plane. A charge of uniform density (3.0 nC/m^2) is distributed over the parallel plane defined by z = 2.0m. Determine the magnitude of th electric field for any point with z = 3.0 m.

Thanks for any help given, this question is a little tougher, I assume its a few steps in solving, just don't know where to go. Thanks for the help :+)
