Question

Coulomb's law is valid for

• A. charged particles separated by atomic distances $\left(\right. \left(10\right)^{- 11} \text{ m} \left.\right)$ .
• B. charged particles separated by nuclear distances $\left(\right. \left(10\right)^{- 15} \text{ m} \left.\right)$ .
• C. charged as well as uncharged particles separated by any distances.
• D. charged particles separated by any distances.

Answer 1

Answer: (D)

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