    i here we have to use the concept of potential due to entire system.

    eduncle-logo-app

    potential of sphere itself and due to spherical body as well.

    good

    eduncle-logo-app

    tnqq chandra sir.

    eduncle-logo-app

    dear here in these two method second is empirical

    for any doubt you can ask..

    eduncle-logo-app

    remember the formulas of potential

    eduncle-logo-app

    due to inducting spherical shell

    eduncle-logo-app

    derive the formulas first then try to remember the formulas

    eduncle-logo-app

    I always Suggest you to make a notes so that it's is way for you to revise formulas

    eduncle-logo-app

    for any query please ask.
