Aproton traveling with velocity 3.60 x 10^4 m/s enters a region of space where there is an electric field e = -5.0 x 10^5 n/c. (a) what is the proton's acceleration?
(b) after it enters the electric field, how much time passes before the proton comes to rest?
(c) how far does it travel in the field before coming to rest?

reserve is the answer

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
