Electrostatics Lec -11 | Electric Field Intensity due to Infinite Sheet of Charges | 2nd Year FSc

Apologies: I forget to write 2 in the denominator in the final expression. Hope you understand. To calculate electric field intensity at a point due to an infinite sheet of charges uniformly distributed Gauss's law is used. We consider a Gaussian surface in the form of a cylinder passing through the sheet and contain point P on one of its faces. The surface charge density (sigma) is the charge distribution on the sheet per unit area. To calculate the electric flux of this Gaussian surface we divide this surface into three parts: two end faces and one curved surface. Flux through curved surface will be zero as the electric field lines E and the area vector A are perpendicular in this case. Then flux is calculated using Gauss's law and compared with the above result.
