(7) Consider a particle that moves going from the point (-2, 2) to the point (-2, 2) along the
piecewise-linear path C depicted below:
(-3,2)
(-2,-2)
This particle is subject to a force field given by
F(x, y) F
2x+y
2y - 2
2² +3² 2² +2²
(a) You can use WolframAlpha to check that the (scalar) curl of Fis 0 on R² - {0}. However,
because R²- {0} is not a very nice set, we can't guarantee that F is conservative. In fact, show
that there exists no scalar function g such that F= Vg.
