A proton with an initial speed of

450,000 m/s is brought to rest by an electric field.

Part A

Did the proton move into a region of higher potential or lower potential?

Because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.

Because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.

Because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.

Because the proton is a negative charge and it accelerates 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 proton?
