- ANewtons 3rd Law of Motion.
- BNewtons 1st Law of Motion.
- CNewtons 2nd Law of Motion.
- DAll of the above.
Explanation:
Coulomb's law agrees with Newton's 1st, 2nd and 3rd law of motion. Coulomb's law states that $\text{F}=\text{K}\frac{\text{q}_1\text{q}_2}{\text{r}^2}$ here the two charge particle is similar to the objects of the Newton's 1st law. Newton's 3rd law is same as the two similar charge particles repel to each other. Which coincides with Newton's 3rd law every action there is an equal and opposite reaction.
