Question

The law which governs the force between electric charges is known as?

Answer 1

Coulomb's Law:

1. According to Coulomb’s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
2. It acts along the line joining the two charges considered to be point charges.
3. The figure illustrates coulomb's law:

In the figure, $q_1$and $q_2$are the electric charges,$‘\mathrm{r}’$is the distance between the charges (center to center). $F_{12}and{F}_{21}$ are the forces on each charge by the other charge.

The mathematical expression of Coulomb's Law is given by:

$F=k\frac{q_1{q}_2}{r^2}$,

Where $k=\frac{1}{4{\mathrm{\pi \epsilon }}_0}$ and ${\epsilon }_0=8.85x{10}^{-12}\frac{C^2}{N-m^2}$

Hence, the law governing force between charges is given by Coulomb's law.
