A proton with an initial speed of 850,000 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? O 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. O 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.
