D) toward the right 
E) zero

Quizplus · Accepted Answer

According to the right-hand rule, the force on a current-carrying wire in a magnetic field is perpendicular to both the field direction and the current direction. In this case, the current is into the page and the field is directed to the left, so the force will be upward, toward the top of the page.
