A charged particle is moving in a cyclotron, what effect on the radius of path of this charged particle will occur when the frequency of the ratio frequency field is doubled?
Correct answer: D. Remain unchanged
- A. It will also double
- B. It will be halved
- C. It will increase four times
- D. Remain unchanged
Explanation
It will remain unchanged. As the frequency of revolution in a cyclotron υC=Bq2πm is independent of r. So the radius of the path in the dees will remain unchanged.

About Charged Particle in a Magnetic Field
A charged particle moving through a magnetic field experiences the Lorentz force, which is perpendicular to both its velocity and the field. The motion may be circular or helical, with questions involving radius, angular frequency, time period, and work done. A stationary charge feels no magnetic force.
