I have a problem exactly like problem 4.10 in griffiths, however that problem is not being much help since it seems to me that they just plug in P(r).

For those who do not have griffiths the question is:

A sphere of radius R carries a polarization P(r)=kr

where k is a constant and r is the vector from the center

2. Relevant equations

[tex]\sigma[/tex]=P*nhat

3. The attempt at a solution

answer is sigma=kR

Thanks
