The discussion revolves around calculating the electric field E in cylindrical coordinates, specifically focusing on the charge density ρ as a function of the radial distance r. Participants are exploring how to approach this problem using concepts from electromagnetism.
The discussion is ongoing, with participants sharing their thoughts and seeking clarification on the problem setup. Some have offered suggestions and references, while others are questioning the interpretation of the problem and the terminology used by the lecturer.
There appears to be uncertainty regarding the definitions and expectations set by the lecturer, particularly in relation to the transition from Cartesian to cylindrical coordinates. Participants are grappling with the implications of the charge density being a function of r.

lanedance said:by the way what do you mean by this?
