AP Physics 2
10.5 Electric Potential
IntermediateMCQGraphicalConceptual13k
A two-dimensional graph in the first quadrant where the vertical axis is labeled Electric Potential V in volts and the horizontal axis is labeled Distance r in meters. A single smooth, continuous curve starts at a high positive value very close to the vertical axis and descends toward the horizontal axis. The curve is concave-up and approaches the horizontal axis asymptotically as r increases, never touching it. At a point on the horizontal axis labeled r subscript zero, a vertical dashed line extends upward to meet the curve. At the point of intersection between the dashed line and the curve, a short, solid straight line segment is drawn tangent to the curve, showing a negative slope. No numerical values or other labels are present on the axes.
Electric potential V as a function of distance r from a point charge +Q.
A stationary point charge \(+Q\) is fixed at the origin. A graph of the electric potential \(V\) as a function of the distance \(r\) from the charge is shown below. Which of the following statements correctly describes a physical property of the system based on the features of this graph?
