This question relates to a point charge + Q fixed in position, as shown in the diagram. Five points near the charge and in the plane of the page are shown.
At which point will an electron experience a force directed toward the top of the page?
Select an Answer
The correct answer is point E, which is directly below the point charge + Q. The electron is negatively charged and since unlike charges attract, it will always experience a force directed straight toward the charge + Q, which is fixed in position. The only labeled point where a force toward + Q is directed toward the top of the page is point E.
