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

question 108

Multiple Choice

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|.

Definitions:

Pacemaker Cells

Specialized heart cells that control the heart's rate by generating and conducting electrical signals.

Left Atrium

One of the four chambers of the heart, receiving oxygen-rich blood from the lungs and pumping it into the left ventricle.

Right Atrium

The right atrium is a chamber in the heart that receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle.

Left Ventricle

The chamber of the heart that receives oxygenated blood from the left atrium and pumps it to the body through the aorta.
