Part Three: Electric Potential Energy Define electric potential energy AND explain how it is similar to gravitational potential energy. (2 marks) If 3.4 ) of work moves a negatively charged particle from the positive plate to the negative plate. How much potential energy did the particle gain? Explain why. (2 marks) What is electric potential? How does it differ from electric potential energy? (2 marks) Calculate the electric potential difference between two parallel plates 3.00 mm apart and an electric field of 60 V/m. (2 marks) The potential difference between two parallel plates is 24.0 V and the uniform electric field between the plates is 80.0 V/m. Calculate the distance between the plates. (2 marks)
