    here note, first find the bound charge density then e.f ... total bound charge for shell is zero that's why e.f outside the shell is also zero.

    is this solution okay to see?

    first term is charge due to surface charge density and second term is charge due to volume charge density...

    eduncle-logo-app

    first term is charge at r=a (due to surface charge density) that's why it is -k/a*4Ο€ square of a...

    eduncle-logo-app

    and second term is charge due to volume charge density .

    mam, i have very very high power for my eyes. hence its very difficult to acess that pic. if u sent a hand write it will very helpful to me

    eduncle-logo-app

    yeah, sure...

    for doubt plz ask dear

    eduncle-logo-app

    mam, in first case p=0 and D=0 then E should be equels to zero. then how can u say that it is E=-k/r abdolo

    eduncle-logo-app

    dear it is in polarizing medium or in dielectric

    eduncle-logo-app

    and yes ofcourse r
