FIGURE 23-12
-Fig. 23-12 shows the variations of the electric potential V (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 electric field along the x axis?

A) E is positive from x = -2 to x = 2.
B) E is positive from x = -2 to x = 0, and negative from 0 to x= 2.
C) E is negative from x = -2 to x = 0, and positive from 0 to x= 2.
D) E is negative from x = -2 to x = 2.
E) More information is needed to answer the question.
