An electron travels to the right, as shown in the figure below, starting in a region of zero magnetic field, and then entering a region of uniform magnetic field, pointing into the page, with a magnitude of
b = 1.10 mT.
The right half of the diagram is filled with crosses and is labeled B = b. The left half of the diagram has no crosses and is labeled B = 0. A particle labeled e minus is positioned in the left half of the diagram. An arrow labeled vector v points from the particle to the right.
(a)
Once the electron enters the region of nonzero magnetic field, it travels in a complete semicircle before exiting the region of field again. (That is, it exits the region moving to the left.) How long (in s) is the electron in the region of nonzero field?
s
(b)
The electron penetrates a maximum depth of 2.10 cm into the region of nonzero field. What is the kinetic energy (in eV) of the electron?
eV

• An electron, at rest, is accelerated through region 1, which has a 5000 V potential difference. It then enters region 2 where there is only a uniform magnetic field and it undergoes uniform circular motion (in a plane) of radius 0.954 mm. After subtending half a circle, the electron exits region 2, traveling in the opposite direction it was before entering region 2. (a) Draw a physical representation of this situation, complete with the direction of the electric and...
