Analysis:
We should try and analyse, by what means or method does any charged
particle, (e.g. proton or electron) measure the distance between itself
and any other charged particle? How does it always gauges the distance
so precisely?
Distance perception (measurement) in space is a striking property
of any elementary particle or point charge. Even human beings, the most
sentient beings on planet, cannot perceive or measure distance in space
accurately. (E.g., I cannot determine the exact distance between my eyes
and my laptop screen without a ruler or scale.)
