Electrical induction and electric field in sphere

AI Thread Summary
The discussion focuses on calculating electric induction D(r) and electric field E(r) for a hollow dielectric sphere with an outer shell. The parameters include a charge q and dielectric constants, with R1 set at 2 cm and R2 at 5 cm. The main challenge is determining how the presence of a hole in the dielectric affects these calculations. Participants suggest using Gauss's law to find D(r) in the dielectric and then deriving E(r) by dividing by the dielectric constant ε(r). The conversation emphasizes the need for accurate graphing and understanding the impact of the sphere's geometry on the electric fields.

Can you get me on tracks with this assignment?

1. Find out and show in graphs electric induction D(r) and electric field E(r) if the field is created by a charge q, which is even in a hollow dielectric sphere. R1=2 cm, R1=5 cm, εa=2ε0So i have a sphere which outter shell is made from dielectric, so i need to calculate eletctric induction only in dielectric sphere? This sphere R would be like R=R1-R2.

and how to find electric field?

Tha main problem is how to calculate with the hole in the dielectric sphere, does it make any differeces?

Calculate the induction D(r) anywhere in the space by Gauss's law in dielectric, and find E(r) by dividing ε(r)
 
Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'
(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
