A negatively charged particle is moving to the right,directly above a wire having a current flowing to the right,as shown in the figure.In which direction is the magnetic force exerted on the particle?
A) into the page
B) out of the page
C) downward
D) upward
E) The magnetic force is zero since the velocity is parallel to the current.

Quizplus · Accepted Answer

According to the right-hand rule for magnetic force, if the particle is moving to the right and the current in the wire is flowing to the right, then the magnetic force will be upward (perpendicular to both the velocity and the current). Therefore, the correct answer is D) upward.
