Ans. The frequency of the cyclotron is inversely proportional to the time period. Meaning, if the expression for cyclotron frequency is:
f = Bq / 2 πm
The time period or the period of rotation becomes:
T = 1/ f = 2 π m / Bq
where B is the magnetic field, q is the particle’s charge, and m is the mass of the accelerated particle.
