The question in question: "If charge was plotted versus electric field strength; what shape of graph would you get? How would you straighten in? What quantity would the slope of the straightened graph represent?" Related equation: |E|= F/q Ignoring the graphing information, the question (as far as I gather) seems to be asking me to rearrange for q/|E|. Now, |E|q = F q = F/|E| q/|E| = F/|E|^2 From that, plotting charge versus field strength results in Force versus the square of the field strength. Which doesn't seem very helpful at all. The units there are C/(N/C), or C^2/N. So, my issue: Am I going about this in the right way? If so, where do I go from here? Does C^2/N represent anything of worth? At a bit of a loss here, so any help would be greatly appreciated.
