Homework Statement
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
Homework Equations
U=Eqd; U=kq1q2/r; V = Ed; V = kq1/r.
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.
