What is a point dipole?
(N/A) point dipole is defined as an electric dipole where the separation distance between the two charges,$2a$,approaches zero $(2a \rightarrow 0)$ and the magnitude of the charges,$q$,approaches infinity $(q \rightarrow \infty)$,such that the product $p = q \times 2a$ remains a finite constant.
In this limit,the dipole is considered to be concentrated at a single point.
