Question 40 14 $.5 The graph in the figure shows the variation of the electric potential V(x) (in arbitrary units) as a function of the position x (also in arbitrary units). Which of the choices below correctly describes the orientation of the x-component of the electric field along the x-axis? 3- 2.5 2 1.5 V(x) -0.5 -2 -1.5 -1-0.5 0.5 1 1.5 2 x O Ex is negative from x=-2 to x = 0, and positive from x = 0 to x = 2. O Ex is positive from x = -2 to x = 2. O Ex is negative from x = -2 to x = 2 Ex is positive from x = -2 to x-0, and negative from x = 0 to x = 2. Areas none of the given choices 2 pts Question 39 Suppose you have two negative point charges. As you move them farther and farther apart, what happens to the potential energy of this system relative to infinity? none of the given choices more information is needed 2 pts O It decreases. O It stays the same. O It increases.
