For coulomb force to be operative the least side of atom will be

View answer and explanation

Correct option: B

10^{-15} \mathrm{~m}

Option B (

10^{-15} \mathrm{~m}

) is correct because Coulomb's law is effective at very short distances, such as the diameter of the nucleus, which is around

10^{-15} \mathrm{~m}

.
