An clectron enters a region of space containing a uniform 1.25 x 10-5 T magnetic ficld. Its speed is 1.5 x 10® m/s when it enters perpendicularly to the ficld. Under these conditions, the electron undergoes circular motion. (a) Find the radius r of the electron's circular path. (b) Find the frequency f of the circular motion.
