When a plane sheet is given a charge Q the electric field at any point around it is given as ##E = \frac{\sigma}{\epsilon_0}##. Thus mathematically it can be concluded that the electric field is constant everywhere and is independent of distance of the point from the sheet. But what logical explanation can be given for this?
Since electric field due to a point charge varies inversely with ##r^2## and a plane charged sheet is nothing but collection of such charges then why the electric field is constant?It would even imply that if I charge a plane sheet on Earth its effect could even be felt on mars?
How is that possible?
