Why is the Coulombian force called a two-body force?
(N/A) The Coulombian force is called a two-body force because the electrostatic force between two point charges depends only on the magnitudes of those two charges and the distance between them.
It is independent of the presence or absence of any other third charge in the vicinity.
Mathematically,according to Coulomb's Law,$F = k \frac{|q_1 q_2|}{r^2}$,where $q_1$ and $q_2$ are the two interacting charges.
Since the force is determined solely by the interaction between these two specific bodies,it is classified as a two-body force.
