A charged particle of mass m = 5.1X10-8 kg, moving
with constant velocity in the y-direction enters a region
containing a constant magnetic field B = 1T aligned with the
positive z-axis as shown. The particle enters the region at (x,y) =
(0.68 m, 0) and leaves the region at (x,y) = 0, 0.68 m a time t =
863 μs after it entered the region.
