Question

If a proton and electron both move through the same displacement in an electric field, 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.)


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

Explanation / Answer

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