Hello,
I have puzzled myself with a question: what is the potential of a conducting rod in a homogeneous electric field (net rod charge = 0)? To be more exact I imagine a conducting rod suspended on a non-conducting thread in the Earth electric field near and perpendicular to its surface. If the rod is in contact with the the Earth then its potential is the ground potential. What confuses me is that a conductor is in contact with variable potentials across its length but the rod must have only one certain value due to charge balance. Any help is very appreciated.
