Question

In cyclotron the resonance condition is :

• A. the frequency of revolution of charged particle is equal to the frequency of A.C. voltage sources
• B. the frequency of revolution of charged particle is equal to the frequency of applied magnetic field
• C. the frequency of revolution of charged particle is equal to the frequency of rotation of earth
• D. the frequency of revolution of charged particle, frequency of A.C. source and frequency of magnetic field are equal

Answer 1

The correct option is A the frequency of revolution of charged particle is equal to the frequency of A.C. voltage sources

In cyclotron the frequency of the revolution of charged particle,

that is $f=\frac{V}{2\pi R}$,

will be equal to frequency of the ac voltage source in resonance condition.
