2) An electron is traveling at 500,000 meters per second. The electron gradually comes to a stop. a. Did the electron move into a region of higher potential of lower potential?

Step 1
For a charge q in an electric potential V, electric potential energy is U = qV. For an electron, q = -e, so U = -e V. Show more…

An electron with an initial speed of 540,000 m/s is brought to rest by an electric field. Part A Did the electron move into a region of higher potential or lower potential? Because the electron is a negative charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential. Part B What was the potential difference that stopped the electron?

An electron with an initial speed of $500,000 \mathrm{m} / \mathrm{s}$ is brought to rest by an electric field. a. Did the electron move into a region of higher potential or lower potential? b. What was the potential difference that stopped the electron?
As an electron moves through a region of space, its speed decreases from $8.50 \times 10^{6} \mathrm{m} / \mathrm{s}$ to $2.50 \times 10^{6} \mathrm{m} / \mathrm{s}$ The electric force is the only force acting on the electron. (a) Did the electron move to a higher potential or a lower potential? (b) Across what potential difference did the electron travel?
