I have been working on this given question for a while now, and it's supposed to be really easy, but I can't get the answer can you sort of guide me through this question, and show me the steps and equations you used?
Question: At what distance from a point charge of 8.0 x 10-6 C would the electrical potential be 4.2 x 104 V?
Please explain each step and equations used to solve the above question.
