Electric Intensity Due To An Infinite Sheet Of Charge. Assume we have a plane sheet of infinite extent on which the positive charges are uniformly distributed.
Now imagine a cylinder passing through this sheet.
The charge enclosed by the surface is A.
The first face of the infinite sheet
Second face of the infinite sheet
Third face of the infinite sheet
The total net flux will be determined by
According to the Gauss’s law
Since is the charge density, Q can be considered as Q=.A
A and A will be canceled out.
This leads us to
