Question

An infinite plane of charge with charge density -3.9uc is 2.2cm away (and perpendicular to) from an infinite conducting slab of charge density 81uc, what is the magnitude of the electric field half way between the two slabs? Ive been working on this for some time now and seem to be doing something wrong. Please Help

Answer 2

I know the field for each plane is sigma/2e0, and i used superposition in all possible ways i could think of, calculating them separately and what not but still am not coming up with the right answer!
