(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A charge q sits in a spherical hollow inside a spherical conductor.

q is located at r=0

Hollow from r = 0 to r =a

from r=a to r=b a conductor

r=b to r = infinity free space

Find the potential everywhere

2. The attempt at a solution

I calculated these

[tex] E = \frac{1}{4 \pi \epsilon_{0}} \frac{q}{r^2} \hat{r} [/tex]

for r<a and r> b

E= 0 for a<r<b

To find the potential from 0 to r=a is what concerns me... We end up having hte potential blow up in at the origin.

it is late and im not thinking striaght but i cant see a way out ....

please help!
