I had a question with two parallel conducting plates with voltages of +30V and -10V, with a separation of 0.2m. This got me thinking, at a certain point (0.15m from +30V plate) wouldn't the electric potential be 0? At the bottom (when a charge touches the -10V plate), wouldn't the electric potential be -10V?
I learnt electric potential as the amount of energy a charge would get if it was placed at that point, so it seems that at 0.15m the charge would not move yet intuitively I feel like it should because it's in an electric field. And at the bottom, the charge would have negative energy? Wouldn't it have 0 energy as the postive test charge unites with the negative plate?
