MCQ
Coulomb's Law is true for:
- AAtomic distances (=10-11m)
- BNuclear distances (=10-15m)
- CCharged as well as uncharged particles
- DAll the distances
✓
Answer
- All the distances
Explanation:
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 $\text{F}=\frac{\text{q}_1\text{q}_2}{4\pi\in_\circ\text{r}^2}$
$\Rightarrow\text{F}\propto\frac{1}{\text{r}^2}$
