Question

State Coulomb's law and express it in vector form.

Answer 1

Coulomb's law states that the electrostatic force between two point charges is directly proportional to the product of charges and inversely proportional to the square of distance between them.

${\overrightarrow{F}}_{12}=\frac{1}{4\pi {ϵ}_o}\frac{q_1{q}_2}{r_{12}^2}\widehat{r_{12}}$
