So I am extremely confused at the moment. We had a hollow ring in physics lab today. There was a positive charge (30V) inside the sphere that was no centered and then the ground was attached to the ring itself (0 V). So, I understand that the negative charges unevenly distribute to cancel the charge on the inside. To my understanding, the positive charges on the outside of the ring would be evenly distributed. Now, I'm not sure if this is correct because my TA said this is only true when the ground is not connected. So, what is the difference in distribution for conductors when there is a ground present and when there is none on both the outside and the inside.
I understand that when the ground is not present, then the ring will have a positive NET charge and there will be a field on the outside of the ring. When the ground is present, it allows the ring to cancel out the charge and there to be no NET charge on the ring. Am I correct? Thanks!
