i have a question I dont know how to answer:
Explain why the potential integral formula cannot be used to directly determine the potential from an infinite uniform line charge ρlo that is on the z axis.
When we talk about it in class, I learn that the potential integral was used for finite displacement. I read the textbook but I did not have other information.
So I there other reason to answer this question? This concept of infinity is a little vague for me.
