Question

Coulomb's Law is true for

• A. atomic distances ($={10}^{-11}m$)
• B. nuclear distances ($={10}^{-15}m$)
• C. charged as well as uncharged particles
• D. all the distances

Answer 1

The correct option is D all the distances

Coulomb's law is true for all distances whether it is small and large. Hence it is called a long range force.

Coulomb's force $F=\frac{q_1{q}_2}{4\pi {ϵ}_o{r}^2}$

$⟹$ $F\propto \frac{1}{r^2}$
