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 = 1.45 mT.
(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 3.15 cm into the region of nonzero field. What is the kinetic energy (in eV) of the electron?
eV

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
