Boundary conditions for field in dielectric around uncharged conducting sphere

[siddharth]

I know what the form of the solutions is but I cannot apply boundary conditions if I do not know what they are. Please answer my questions.

Ok, if you type the form of the solution in your next post, it might help.

Because, if you do that,
(i) you will see how many constants you need to evaluate
(ii) you will be able to figure out what bc's to use (ex, what happens to V at r=b? What happens to its derivative)
(iii) once you find the solution, you will see what happens at r=a (ex, what is dV/dr at r=a)
