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.
