An electron (mass = 9.11 x 10-31 kg) has a speed of 6000 m/s. The electron's velocity is perpendicular to a uniform magnetic field, so the electron follows a circular path. The field is into the page, and has a magnitude B = 0.15 T.
How long does it take for the electron to travel once around this circle?
