Sphere with dipole in a dialectric

  1. Dec 9, 2015 #1
    1. The problem statement, all variables and given/known data
    Evaluate the electric field of a hollow sphere with a dipolo , in a dialectric. See left figure..

    2. Relevant equations
    $$\alpha \vec{p}$$

    3. The attempt at a solution
    I dont understad why at the field electric "in" there is a term of form $$\alpha \vec{p}$$ , and term $$\beta$$ "out.

    I thinking that the dialectric is polarized and create a field electric as the right figure, but i dont sure.....
