1. The problem statement, all variables and given/known data A particle with charge q experiences a force F when placed a distance d from a point charge. At a distance d, the electric field has a strength E and a potential V. Which of the following represents the potential energy of the charge? (A) Fd (B) Eqd (C) Vq (D) Ed 2. Relevant equations U=Eqd; U=kq1q2/r; V = Ed; V = kq1/r. 3. The attempt at a solution I chose B but the correct answer is C. We know that the potential energy of a charge in an electric field is the force times the displacement: U = Eqd. What is the difference between answer choice B and C? Thanks in advance and if I didn't provide enough explanation for my question, please let me know.
