Consider the figure above. The blue ball at (-1,1,0) carries a charge Q, and the green ball at (1,-1,0) carries a charge -Q. A small positive test charge q may be moved from (0,-3,0) to (0,3,0) by two routes:

Route 1: straight along the y-axis
Route 2: a path with two diagonal elements passing through the point (-2,0,0)

Which of the following statements is true?

1. Route 1 requires more work than Route 2.
2. Route 2 requires more work than Route 1.
3. Both routes require zero work.
4. The routes require an equal, positive amount of work.
5. The routes require an equal, negative amount of work.
6. There is not enough given information to decide which path requires more work.
