    no ma'am you please tell me my previous question that how it is showing charge inside a sphere because charge density is zero inside hollow sphere????

    see dear it's ur last doubt

    eduncle-logo-app

    sir please tell me about how charge density in hollow.....

    eduncle-logo-app

    The surface charge density is present only in conducting surfaces and describes the whole amount of charge q per unit area A.

    mam please provide me derivation of last one also. and tell me about my above question!!!??

    eduncle-logo-app

    ok m giving you proper derivation of potential.

    dear region for their difference is that one has charge distribution on surface while another has charge distribution on volume.

    eduncle-logo-app

    ok mam for solid is here I understand but what about hollow because inside hollow sphere charge density is zero

    eduncle-logo-app

    m attaching see that

    eduncle-logo-app

    charge density will zero but not potential.
