Q. Consider a metallic particle rotate with high speed on the top of a dielectric bar (like ceramic) around the other side of the bar. what is the electric potential energy of this particle? is there any equation?

Q. An electron is released from rest in a vacuum between two flat, parallel metal plates that are 11.0 cm apart and are maintained at a constant electric potential difference of 620 Volts. If the electron is released at the negative plate, what is its speed just before it strikes the positive plate?
