An electron with an initial speed of 380,000 m/s is brought torest by an electric field.

1.

Did the electron move into a region of higher potential or lowerpotential?

A. Because the electron is a negative charge and it slows downas it travels, it must be moving from a region of lower potentialto a region of higher potential.

B. Because the electron is a negative charge and it slows downas it travels, it must be moving from a region of higher potentialto a region of lower potential.

C. Because the electron is a positive charge and it acceleratesas it travels, it must be moving from a region of lower potentialto a region of higher potential.

D. Because the electron is a positive charge and it acceleratesas it travels, it must be moving from a region of higher potentialto a region of lower potential.

2. What was the potential difference that stopped theelectron?

Express your answer with the appropriate units.

3. What was the initial kinetic energy of the electron, inelectron volts?

Express your answer in electron volts.
