I just want to make sure my understanding in this topic is correct. Positive charges will spontaneously move in the direction that lowers their electric potential (V), where as negative charges will spontaneously move in the direction that increases their electric potential. This in turn makes positive charges going with a uniform E field lines, and negative charges going in the direction opposing the direction of the E field lines. However, both charges will move in the direction that decreases their potential energy, and thus stabilize the system more.
Here is a question then that I am in conflict with:
"A charged particle goes from point i to point f in the presence of and electric field E. The change in the potential energy as the particle moves from i to f depends on the charge" True or False
I stated false because the change in potential energy as the particle moves from i to f will decrease independent of the type of charge. If this were talking about the electric potential then I would state true. The answer key however disagreed with my choice and stated the answer as True. I'm thinking it must be a typo, but require confirmation.
Thanks.
