f a proton and electron both move in an electric field through the same displace

Question

f a proton and electron both move in an electric field through the same displacement, is the change in potential energy associated with the proton equal in magnitude and opposite in sign to the change in potential energy associated with the electron? (Select all that apply.)

The magnitude of the change is larger for the proton.
The signs of the two changes in potential energy are opposite.
The signs of the two changes in potential energy are the same.
They are equal in magnitude.
The magnitude of the change is smaller for the proton.

Explanation / Answer

They are equal in magnitude. The signs of the two changes in potential energy are opposite.
