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

question 32

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|.
