Consider the force field shown in the figure.

(a) Give a verbal argument that the force field is not conservative because you can identify two paths that require different amounts of work to move an object from (-4, 0) to (3, 4). Of the two paths, which requires the greater amount of work?

(b) Give a verbal argument that the force field is not conservative because you can find a closed curve C such that ∫c F ^. dr ≠ 0.
