Section 2.6 starts out with the problem of a "conducting sphere" near a point charge, but then it confusingly veers away to a problem where potential is prescribed to vary with azimuth and polar angle. So my question is: can somebody verify that the solution at the end of Section 2.6 is NOT for a conducting sphere? After all, a conducting sphere would NOT have potential varying in the azimuth etc...

Further, if it's NOT a conducting sphere then what is the interaction between the "nearby point charge" and the sphere? Is it a dielectric sphere? Is it a completely non-interacting sphere?
