The frequency of cyclotron is given as:
Correct answer: C. qB/2πm
- A. qBr/2πm
- B. qBr/2π
- C. qB/2πm
- D. qB/2πrm
Explanation
q v B = m v² / r⇒ q B = m v / r = m (r ω) / r = m (2 π f)⇒ f = q B / (2 π m)

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
