Question: Question 2 Suppose a charged particle P moves in a curve C in A from a point A = (-7, 7) to a point B

Question 2 Suppose a charged particle P moves in a curve C in A from a point A = (-7, 7) to a point B = (7/4, 4) through an electric field which exerts a force on P. Experiments suggest the force is modelled by a 1-form w = cos a cos ydx - sin x sin ydy. Show that w is exact. Hence or otherwise calculate the change in potential energy Jow when moving from A to B.
