Let's say I have a sheet of charge that is composed of a certain amount of charged atoms summing up to Q and a certain area A. The charge density would be Q/A = σ. I wish to find the elctrostatic potential from the sheet at point X. I believe that the electric potential should follow the equation: V = (σX)/ ε_0 However, shouldn't the potential decrease as I travel away from the sheet? If I have a sphere of charge and I travel away from it, then this is the case. Why is this situation different? EDIT: I meant sheet in the title ofthe post. I just had the sphere idea in my mind at the time!
