Questions 11-12

A uniform magnetic field B directed downward parallel to the plane of the page exists in the shaded region shown above. An electron can enter the field from different directions.

11）Suppose that the electron is moving straight down in the same direction as B when it enters the region of the magnetic field. What is the direction of the magnetic force, if any, on the electron when it first enters the field region?

1. Toward the bottom of the page
2. Toward the top of the page
3. To the left
4. To the right
5. None; there is no magnetic force on the electron

12）Suppose that electron is moving perpendicularly into the plane of the page when it enters the region of the magnetic field. What is the direction of the magnetic force, if any, on the electron when it first enters the field region?

1. Toward the bottom of the page
2. Toward the top of the page
