Two square metal plates are placed parallel to each other, separated by a distance d= 2.34 cm. The plates have sides of length L= 0.750 m. One of the plates has charge Q=+ 2.70 x10-3 Coulombs, while the other plate has charge -Q. What is the magnitude of the electric field between the plates, not close to the edge?
C = AE0 / d
E = kQ/r
The Attempt at a Solution
I know how to find the capacatance of the plates, but I don't know how to translate that to the electric field?
I tried to just use kQ/r, but that was incorrect. I'm not sure where I'm going wrong, could someone help?
