The Electric Field in the Region Defined by the Y-Z

question 86

Multiple Choice

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|.
