The time period is given as
T = 2πm / Bq
where
mass of the electron, m = 9.1 X 10-31 kg
magnetic field strength, B = 0.2 mT = 0.2 X10-3 T
charge on the electron, q = 1.6 X10-19 C
so,
T = (2 X3.14 X 9.1 X 10-31) / (0.2 X10-3 X 1.6 X10-19)
or
T = (57.148/0.32) X 10-9
thus, the time period will be
T = 1.785 X 10-7 secs.
