	When a particle of charge q and mass m enters the uniform magnetic field B moving with velocity v perpendicular to the direction of the field the time required by a charged particle to make a complete revolution in a magnetic field is given by

M.maroof Aslam said:

q/m = v/Br r/v = m/Bq r/r/sec = m/Bq 1/1/sec = m/Bq sec = m/Bq or T = m/Bq the final relation is derived
