[QUOTE="LCSphysicist, post: 6431920, member: 675151"] [B]Homework Statement:[/B] n [B]Relevant Equations:[/B] \ [ATTACH type="full" alt="1608237510522.png"]274558[/ATTACH] I am rather confused how to answer this (Please focus on "find the potential at the center"): I thought that would be a good idea try to answer this with the Poisson equation. $$\nabla \phi = - \frac{\rho}{\epsilon}$$ So that, since the eletric field inside a hollow spherical shell is zero, the potential at the center is just equal to the potential at R1. I found this solution $$\phi = \sum K_{i}(\frac{\rho(R_{2}^2-R^2)}{6 \epsilon} + C(\frac{1}{R_{2}}-\frac{1}{R}))$$ But i have no idea how to go on [/QUOTE]
