Homework Statement
There's three thick, conducting concentric spheres with radii R1, R2, R3 (R1 < R2 < R3) with charge Q1, Q2, Q3 respectively.
a.- The middle one is now wired to the ground. Find its net charge
b.- The internal and external spheres are now wired. Find the distribution of all the charges
Homework Equations
The Attempt at a Solution
I think that when you wire to conductors, they have the same potential, but I'm clueless on how to apply this (if it's what I'm supposed to use at all).
