Expert Answer
Coloumb's law expressess the electrical interaction between two charged bodies in terms of the forces they exert on each other. Point charges are charges whose dimensions are negligibly small, compared with the distance to another charged body. One of the limitations of coloumbs law is that it is applicable only to point charges. i.e. the electric charges must be point in size. Coloumb's law does not apply to two charged bodies of finite sizes like two charged spheres. It is because the distribution of charge does not remain uniform when the two bodies are brought together.
