This is an equation for an radially directed, electric field of a rod that has finite charge and is uniform. r is the distance of the charge in a plane that bisects the rod. L= length of the rod, Q= Total charge of the rod, k=coulomb's constant. if k=1 units, Q=1 units, L=12 units, what is Erod when r=4?
A cylinder of length L=5m has a radius R=2 cm and linear charge density 2=300 µC/m. Although the linear charge density is a constant through the cylinder, the charge density within the cylinder changes with r. Within the cylinder, the charge density of the cylinder varies with radius as a function p( r) =p.r/R. Here R is the radius of the cylinder and R=2 cm and p, is just a constant that you need to determine. b. Find the constant po in terms of R and 2. Then plug in values of R and 1. to find the value for the constant p. c. Assuming that L>>R, use Gauss's law to find out the electric field E inside the cylinder (rR) in terms of 1. and R. d. Based on your result from problem c, find the electric field E at r=1cm and r=4cm.
A thin rod is bent into a half circle of radius R and centered on the y-axis so that it lies flat in the xy-plane as indicated in the diagram.

A rectangular box (L = 30 cm, w = 28 cm, h = 11 cm) has a net charge gencl enclosed inside it. The figure below shows three electric fields, each pointing to the left, measured on the surface of the box. E₁ is uniform over the right side of the box, E2 is uniform over the top, bottom, front, and back sides, and E3 is uniform over the left side. If the magnitudes of the electric fields are E₁ = 550 N/C, E₂ = 900 N/C, and E3 = 1300 N/C, determine the value of gencl. Note that the figure is not to scale. με Ē₁ L E W h
