Furthermore, how does an electron or proton measure its own charge
amount? By what means they are able to do so? Are they self-aware?
By what method it measures the charge quantity of any charged particle
placed in its vicinity? How does it differentiate between the nature of
that particle, whether it is negatively charged or positively charged?
And after all this data collection by any fundamental particle, it
applies the needful force?
Perhaps, these are the ultimate fundamental questions to be scrutinized.
At least, we cannot deny the fact that it is doing so (or it is
happening). Because, by denying it, we would probably be denying
coulombs law.
