Conformal mapping is an elegant procedure when it works. It is a good technique in 2-D rectangular x , y or cylindrical r , R. ) ( ) geometries with sufficient symmetry that a mapping function can be found that transforms the boundaries into a simple rectangle or circle. A cylindrical r , z geometry is not useful.

Solution: The magnitude of the electric force between two point charges q and q′ located at distance r from each other is given by the Coulomb's law as follows. =. q q′|. k. r2. Where k = 9 × 109 N · m2/C2. The directions of forces the two charges exert on each other are always along the line joining them.
