What are the limitations of Coulomb's Law ?
Coloumb’s law has the following two limitations:
The charges should be point charges i.e the charges are placed at a point which have no dimensions
The second limitation is the distance between the two charges remains constant.
The third limitation of Coloumb’s law is that the charges should not radiate any amount of energy. For eg in Bohr’s postulate, Coloumb’s law is applicable to the electron moving around the nucleus as it is assumed that the electron does not radiate any energy.
