The discussion revolves around Gauss's Law, specifically focusing on determining the electric field (E(P)) and electric potential (phi(P)) at a point P, given certain parameters R and Q. The original poster expresses uncertainty regarding the problem setup and the relevant equations.
The discussion is ongoing, with participants actively seeking clarification on the problem's parameters and configuration. Some guidance has been provided regarding the need for more specific information, but no consensus or resolution has been reached yet.
There is mention of a potential mistake regarding the variable R, and the original poster acknowledges a lack of clarity about the point P and its relation to the charge configuration. The absence of a visual reference for point P is noted as a constraint in understanding the problem.

Could you be more specific? What is R for instance? What is P? What are you looking for?
lidl said:sorry for this R! mistake.
now i am looking only for the electric potential (sigma) at the point P!
