this is my first and second questions. I'll start with my assumptions and go from there to ask my questions. Please do not hesitate to correct me if any of these assumptions are wrong.
Inside of a Faraday cage there is no Electric field present as in a closed spherical shell. There is no charge on the inside surface of the said Faraday cage either. So if you are inside, you feel no Electric field.
This being said, if one has two infinitely large (similarly charged) parallel plates made out of conducting material (copper, gold or silver) as in a capacitor-like design, and one stands right in the middle (centre), between the two plates, will one feel an electric field?
I do know it is not a closed surface but realize the plates are infinitely large, and there is enough charge so that Q/area never equals 0.
In other words, do I absolutely require the closed surface (triangular pyramid- minimal faces to spherical shell-maximal faces) in order for Gauss' law to be valid.
Thanks in advance!
