5 Electrical Problems You Should Never Resolve By Yourself
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.
