This discussion revolves around a problem from Griffiths' Electromagnetism textbook, specifically questioning the applicability of special relativity in the context of the problem presented. The original poster expresses uncertainty about the relevance of relativity to the problem, given its placement in Chapter 5.
The discussion is ongoing, with participants exploring different interpretations of the problem and its requirements. Some guidance has been offered regarding the approach to take, particularly in considering force balance, but there is no explicit consensus on the application of special relativity or the solution path.
There is a mention of gamma factors, which typically indicate relativity effects, but some participants suggest these may not be central to the problem's solution. The original poster has not provided the full problem statement, which may be limiting the discussion.

Usually when gamma factors show up, that means the problem involves a relativity effect, but here that is just a red herring to derive the solution. I'm not 100 percent sure, but I would suggest you think about this problem from the point of view of a force-balance - The pinch from the B-Field versus the electric field trying to keep the wire neutral. The explanation for the ultimately neutral wire does lie in relativity, though.
