Question
The figure below shows the path of an electron in a region of uniform magnetic field. The path consists of two straight sections, each between a pair of uniformly charged plates, and two half-circles.
The upper plate in the top pair is at the higher electric potential.The lower plate in the top pair is at the higher electric potential.Both plates in the top pair are at the same electric potential.The upper plate in the bottom pair is at the higher electric potential.The lower plate in the bottom pair is at the higher electric potential.Both plates in the top bottom are at the same electric potential.The magnetic field is directed up.The magnetic field is directed down.The magnetic field is directed into the page.The magnetic field is directed out of the page.
Explanation / Answer
The upper plate in the top pair is at thehigher electric potential. The lower plate in the top pair is at thehigher electric potential. The upper plate in the top pair is at thehigher electric potential. The lower plate in the top pair is at thehigher electric potential. Themagnetic field is directed into the page.
