Electric Field Problem

  1. Sep 8, 2008 #1
    1. The problem statement, all variables and given/known data

    An electric field in the region r>a is given by Er=2ACos([tex]\vartheta[/tex])/r3, E[tex]\vartheta[/tex]=Asin([tex]\vartheta[/tex])/r3, E[tex]\psi[/tex]=0 where A= constant. Find the Volume charge density in the region.

    There is not picture.

    I am really lost on this one.

    From what I can read, it seems like you gave the E field in spherical basis vectors. But the method involved doesn't depend on any coordinate basis. Just ask yourself what is another interpretation for div(D).
