Homework Statement
This question refers to Griffiths E and M book.
Of course I am stuck with the integral.
I chose z to be in the same direction as the polarization.
The integral is then
[tex]P \int d\Omega r'^2 dr'\frac{\left(\mathbf{r} -\mathbf{r'}\right)\cdot \hat{\mathbf{z}}}{\left(\mathbf{r} -\mathbf{r'}\right)^2}[/tex]
BTW, how do you get the script r that Griffiths uses in latex?
