Earthed plates confusion

The discussion revolves around the grounding of the third plate in a system of four charged plates and the implications for electric potential and field. It is established that grounding plate three leads to a final net charge of zero on the system, affecting the charge distribution on the plates. Confusion arises regarding the electric field and potential differences, particularly when moving charges between plates, as certain movements require work against an electric field despite the grounding. The participants emphasize the importance of using Gauss's law to analyze the electric fields and charge densities rather than relying solely on potential work calculations. The conversation highlights the complexities of charge distribution in grounded systems and the need for clarity in problem statements.

indigating
Now I'm confused… you previously mentioned "indagate", an archaic but valid word meaning to investigate, from the Latin "indagare". "Indigate", as used in your post #27 seems like a misspelling of "indicate". Though it could be useful to describe e.g. wagging one's finger at a queue jumper, expressing digital indication of indignation all in one go.

I'll explain! In Post #24 you wrote:

I looked at the link. The first (remarkable) sentence of the abstract is this:

"The foremost grail of this academic indagation is to delineate a mathematical expression of the normalised charge density over a flat disk."

Had to look-up 'indagation' and found it meant search or enquiry.

I then felt an ironic compulsion to use it in subsequent posts. Sorry about that!
