An electron traveling left to right enters a region of space
where a uniform magnetic field exists (see figure). Once in the
field, the electron follows a circular path where r = 1.0E-6 m. If
the magnitude of the magnetic field is 5.5 T, what is the speed of
the electron and the direction of the magnetic field?
530 m/s, into the screen
530 m/s, out of the screen
9.7E5 m/s, into the screen
9.7E5 m/s, out of the screen
5.5E-6 m/s, into the screen
