(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Imagine a cylinder of radius R and Length L. Both of it's ends are open and it carries a uniform surface charge desnity of sigma (@) Find the electric potential at any point along the axis of the cylinder, and then use that to calculate the electric field at any point.

2. Relevant equations

3. The attempt at a solution

Essentially the way you are supposed to do this problem (I think) is to assume the tube is just a bunch of stacked line charges (rings), and then find the potential from a ring, and then integrate from 0 to L or something, I'm having real trouble doing so however, any help out there?

Thanks
