Homework Statement
A cylinder of length L and radius R is centered on the z-axis in a region where there is a uniform electric field of E i. Determine the flux for the fourth of the cylindrical surface where x > 0 and y > 0.
Homework Equations
[tex]\phi = \int E dS[/tex]
The Attempt at a Solution
I believe I have the sketch drawn as the problem states.
If you were to take the entire surface, you'd see:
[tex]\phi = \int E dS[/tex]
[tex]\phi = E \int dS[/tex]
[tex]\phi = E (2\pi RL)[/tex]
[tex]\phi = 2E\pi RL[/tex]
I'm confused though. Wouldn't a Guassian surface, such as the cylinder, ultimately have zero flux in the above Electric Field?
I don't know how to progress using Gauss's Law to cut this into a fourth. I don't see how I can use symmetry to develop a method to use the law.
