[1] It is the field described by classical electrodynamics and is the classical counterpart to the quantized electromagnetic field tensor in quantum electrodynamics. We will first calculate the electric field due to a charge elementdq(in red in the figure) located at a distance r from point P. The charge element can be considered as a point charge, thus the electric field due to it at point P is: And the total electric field due to the ring is the following integral: Before evaluating this type of integrals, it is convenient to first analyze the symmetry of the problem to see if it can be simplified. We will also assume that the total charge q of the disk is positive; if it were negative, the electric field would have the same magnitude but an opposite direction. Furthermore, the electric field satisfies the superposition principle, so the total electric field at point P is the sum of the individual electric fields due to both charge elements: As you can see in the previous figure, the vertical component of the vector sum of both fieldsdEis zero. Are you looking to do the integrations by hand? How to calculate Electric Field due to infinite sheet using this online calculator?

Suppose we want to find the intensity of electric field E at a point p1near the sheet, distant r in front of the sheet. Since As are common in both sides, we can divide both sides to eliminate the cross sectional area and that also tells us that it doesnt make any difference how big or how small we choose the cross sectional area of the Gaussian pill box. 4. Even for that, I have a text book at my hand in which the expression is derived using Coulomb's law. All together we find that $E=\frac{\rho}{2 \epsilon_0}$ and the direction we thought already of is some unit vector $\hat{n}$ orthogonal to the infinite sheet: $$ \vec{E} = \frac{\rho}{2 \epsilon_0} \hat{n} .$$.
