A line graph plotting electric potential V in volts on the vertical axis against position x in meters on the horizontal axis. The horizontal axis ranges from 0 to 8 meters with major tick marks every 1 meter. The vertical axis ranges from -15 volts to +15 volts with major tick marks every 5 volts. A bold continuous line consists of four straight line segments connecting five points: point 1 at (0, 0), point 2 at (2, 10), point 3 at (5, 10), point 4 at (7, -10), and point 5 at (8, -10). Grid lines extend lightly across the plotting area at each major tick mark. The point at x = 6.0 meters lies on the linear segment connecting (5, 10) and (7, -10). No other labels, lines, text, or axes appear.
Electric potential V versus position x along the x-axis.
The graph shows the electric potential \(V\) as a function of position \(x\) along the x-axis in a region of space. An electron with charge \(-e\) is placed at rest at position \(x = 6.0\text{ m}\). Which of the following correctly identifies the magnitude of the electric field at \(x = 6.0\text{ m}\) and the direction of the electric force exerted on the electron?
