- Homework Statement
- Hello, this is my first post on the physics forums. Please forgive me if I am not following any post structure well. The question is supposed to use Gauss's Law, but I cannot understand how it would apply to a cylinder that you cannot obtain the surface area of (we are not given L), let alone an object that is not closed. How do you go about this?

- Homework Equations
- (Difficult to write without access to integral and vector symbols.) I am using Gauss's Law and General superposition of an electric field.

I have no idea how to approach the problem using Gauss's Law.

I found the electric field using superposition, and it was incorrect.

I am assuming you treat the wire as a continuous electric field, and then also treat the pipe as a continuous electric field. I solved for this using superposition, but it was incorrect, so then I tried multiplying it by 2πr (circumference) and it was incorrect as well. Maybe I input the wrong values? Any help is appreciated. Thank you.
