A block of width 2d and cross-sectional area infinitely large, it has a homogeneous volumetric charge distribution ρ. Using Gauss's law, find the field electric as a function of the y-coordinate, where the center of the width of the block is located at y = 0. Graph the electric field, considering that this will be positive for y > 0 and negative for y < 0.

In the space between two parallel planes separated by a distance 2d some charge is uniformly distributed with density po. Calculate the electric field in all space as a function of x 2d

We have calculated the electric field due to a uniformly charged disk of radius R, along its axis. Note that the final result does not contain the integration variable r: R. Q/A 2€0 Edisk (x² +R*)* Edisk perpendicular to the center of the disk Uniform Q over area A (A=RR²) Show that at a perpendicular distance R from the center of a uniformly negatively charged disk of CA and is directed toward the disk: Q/A radius R, the electric field is 0.3- 2€0 4.4.1b

There are three static charges (Q1 = 4 nC, Q2 = - 4 nCn and Q3 = - 4nC) located in different locations of Fig. 1. Calculate the net electric field at the given point P.
