In Problems 63 through 66 you are given the equation(s) used to solve a problem. For each of these
a. Write a realistic problem for which this is the correct equation(s).
b. Finish the solution of the problem
(a) Find the Electric field strength at point on the rod's axis at distance from the center of an infinite charge rod, with the linear charge density is in
(b) The solution is
Theory used :
The Electric field of an infinite line charge with a uniform linear charge density can be obtained by a using Gauss' law. Considering a Gaussian surface in the form of a cylinder at radius , the electric field has the same magnitude at every point of the cylinder and is directed outward.
(a) Realistic problem :
On an infinite charge rod, let the linear charge density is .
In , find the electric field strength at point on the rod's axis at distance from the center.
(b) Solution :
You've hung two very large sheets of plastic facing each other with distancebetween them, as shown in. By rubbing them with wool and silk, you've managed to give one sheet a uniform surface charge density and the other a uniform surface charge density . What are the electric field vectors at points,and
