Problem Set 9: Physlet 2

You are given four force fields through which you are to drag an object. The table and the bar graph show the work associated with moving the charge around from one point to another. Which of the force fields can be represented by a potential energy function?

Force Field A Force Field B Force Field C Force Field D


How should a potential energy function behave under a  path that closes on itself ( rinitial = rfinal )?
