Goal: Hone the conservative nature of the electrostatic field

Source: 283-240 Work moving charge around

Two point charges are fixed on the x-axis. A positive charge from point
P to the origin along the different paths shown in the diagram below.
For which path would you do the most work?

  1. Path A
  2. Path B
  3. Path C
  4. Path D
  5. Cannot be determined
  6. None of the above



(6) Relating the work done to the change in potential should be
stressed. Once this point is made, a good follow-up question is to ask
how much work would be done if one of the charges on the x-axis was
