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

Find the average potential over a spherical surface of radius R due to a point charge q located inside.

2. Relevant equations

V(ave)=V(centre) + Q(enc)/(4*pi*epsi*R)

Where V(centre) is the potential at the centre due to all the external charges, and Q(enc) is the total of the enclosed charge.

3. The attempt at a solution

I think what they are asking is, what is the potential where the charge is located, I thought that because at the centre, r=0, then the V is proportional to 1/r, therefore it's not possible. If you can see the question differently, let me know because it's really doing my head in.

Thanks
