# The graph below shows the electric potential \(V\) as a function of position \(x\) along the x-axis in a region of space. Which of the following graphs best represents the x-component of the electric field \(E_x\) as a function of position \(x\) over the same interval?

The graph below shows the electric potential \(V\) as a function of position \(x\) along the x-axis in a region of space. Which of the following graphs best represents the x-component of the electric field \(E_x\) as a function of position \(x\) over the same interval?

![A quantitative graph of electric potential V in volts versus position x in meters. The vertical axis ranges from 0 to 8 V with tick marks labeled 0, 2, 4, 6, 8. The horizontal axis ranges from 0 to 6 m with tick marks labeled 0, 1, 2, 3, 4, 5, 6. From x = 0 to x = 2 m, V increases linearly from 0 V to 6 V. From x = 2 m to x = 4 m, V is constant at 6 V. From x = 4 m to x = 6 m, V decreases linearly from 6 V to 0 V. Vertical dashed lines extend from x = 2 m and x = 4 m. No other labels or lines appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785826358-1INzBS.jpg)
