The electric field in the region defined by the y-z plane and the positive x axis is given by E = ax, where a is a constant. (There is no field for negative values of x.) As x increases in magnitude, relative to V = 0 at the origin, the electric potential in the region defined above is

a. a decreasing function proportional to ?|x2|.
b. a decreasing function proportional to ?|x|.
c. constant.
d. an increasing function proportional to +|x|.
e. an increasing function proportional to +|x2|.
