I have been working on this question for a while now, and it's supposed to be really simple, but I can't get the solution can you sort of guide me through this question, and show me the equations you used?
Question: Suppose the potential due to a point charge is 4.5 x 102 V at a distance of 16 m.
Part I: What is the magnitude of the charge in C?
I need help to solve the above question. Thanks.
