a point charge q is placed a distance d from the center of a conducting spherical shell of radius r (r < d). total charge of the sphere is zero. find the electric potential everywhere. justify your answer.

Can you tell me why the sphere has influence on the potential when there is only one point charege in the space? The link you refered all shows that at least two point charges are in the picture. Find another link?
alitavakol,
Can you explain what does this mean, "we don't know the potential of the sphere. all we know is that its potential is zero"? You don't know its potential but you know its potential is zero?
sorry! I have fixed it.steve10 said:zajbanlik

Obviously, we are going back and forth between those terms, charge, potential, electric field. This is what he said, "Be careful. we don't know the potential of the sphere. all we know is that its total charge is zero ..." Does it mean we have charge on the sphere? The potential and charge are different concepts. The influence is about the potential,but not charge.zajbanlik said:Hello
OK Let's be more detail.
The charge on sphere is not uniform because of the influence of charge q which is outside the sphere (it is in total 0, but that doesn't means that schould be 0 in every point). .....
