Homework Statement
Please stop reading unless you have Griffiths.
In part a, he says that I know the answer in advance. I actually don't. Why should I?
The discussion centers on Griffiths Problem 3.17 from the textbook "Introduction to Electrodynamics." The participant expresses confusion regarding the requirement to know the answer in advance for part a of the problem. They clarify that the absence of higher-order terms in the Legendre Polynomial indicates that the solution must be consistent with the potential outside the surface, relying on the ratios of the radii.
PREREQUISITESStudents of electromagnetism, physics educators, and anyone tackling Griffiths' problems in electrodynamics will benefit from this discussion.
