Question 40 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? 4 $5 3 2.5 1.5 1 0.5 V(x) -2 -1.5 -1 -0.5 0.5 1 1.5 2 x Ex is negative from x = -2 to x = 0, and positive from x = 0 to x = 2. Ex is positive from x = -2 to x = 2. 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. 2 pts none of the given choices
