The Attempt at a Solution
I have next to no clue on how to do this question. My first idea was to try and set up one of the lengths as r, and work from there, but I wasn't able to do anything conclusively. The most confusing part is not being able to do the calculus and relating the variables to fit the purposes of the problem. How exactly do you find the potential of something like this, in general?
Any help for this question will be greatly appreciated.
