Write the limitations of Coulomb's law.
(N/A) $(1)$ Coulomb's law is valid only for point charges.
$(2)$ It is applicable only when the charges are at rest.
$(3)$ It is valid for distances greater than the nuclear dimension, i.e., $r > 10^{-15} \,m$.
$(4)$ It is not applicable for very large distances where other forces might dominate or the assumption of point charges fails.
