Question
Write down the limitations of Coulomb's law.
✓

Answer

►The limitations of Coulomb's law are as follows :
(i) The electric charge should be point charge.
(ii) Charge must be constant.
(iii) This rule does not apply for distance less than $10^{-15} m$
(iv) This force is only applicable when the distance between two electric charges is not more than $10^{18} m$.
(v) From the coulomb's law we can only get the force between two electric charges.
