Homework Statement
Two hollow concentric conducting spheres hold charges Q[1] and Q[2] as shown in the attachment.
Find the potential of each sphere, and the potential difference.
Homework Equations
Potential difference V = Phi[2] - Phi[1]
The Attempt at a Solution
I'm having some trouble with the actual question; what does it mean, the potential of each sphere? Does this mean the potential of the sphere at a distance r where r is greater than the radius? In this case I think the answer would be
Phi[1] = Q[1]/(4*Pi*Epsilon*r)
and
Phi[2] = Q[2]/(4*Pi*Epsilon*r)
I don't think this is quite correct however. Does it mean the potential *on* each sphere instead? In this case, wouldn't the potential on the inner sphere due to the bigger sphere be zero?
I'm quite confused here and any help would be appreciated!
