SUMMARY
The discussion centers on calculating the electric potential of a point outside a charged cylinder, specifically addressing the correct definition of the separation vector in cylindrical coordinates. Participants emphasize the importance of clearly defining the geometry of the charge density, noting that the absence of symmetry complicates the problem. The correct distance formula for the separation vector is established as $$|\vec{r}-\vec{r'}|=\sqrt{(h-z)^2+s^2}$$, derived using the Pythagorean theorem. The conversation highlights the need for precise definitions and clarity in problem statements to facilitate effective problem-solving.
