Two questions:
1.) Consider a hollow conductive sphere that's initially charged. These charges will distribute themselves in such a way that the condition: E-field(inside)= zero is satisfied.
Now consider a hollow conductive sphere with a charged object inside
The charges on the conductive sphere will have a different distribution of course. Said another way, the charges will re-distribute from the original one. But, they will do so to satisfy what condition?
2.) You orient a straight piece of conductor on its long axis to point away from a van de graff generator (r hat)
everyone says that conductors maintain equipotential but the two ends of the conductor you are holding are at different equipotential lines. So is there a ΔV between the conductor ends or not?
intuition tells me that the ΔV induces an initial charge separation within the conductor.
But, it's just that "conductors always maintain an equipotential" thing that gets me wondering.
Thanks all
