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.

Question 2

The electric field in the region defined by the y-z plane and the negative x axis is given by E = -ax, where a is a constant. (There is no field for positive 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.
