Question
The electrostatic force between two point charges $q_1$ and $q_2$ at separation $'r\ '$ is given by $\text{F}=\frac{\text{K}_\text{q1q2}}{\text{r}^2}.$ The constant $K:$
✓
Answer
$\text{K}=\frac{1}{4\pi\epsilon_\circ\text{k}}$ and its units is $N−m^2/ C^2$
It depend on system of unit and dielectric constant $(k),$ that's medium between charges
