What is the angular frequency during the circular motion?
Correct answer: C. qB/m
- A. qm/B
- B. m/qB
- C. qB/m
- D. qmB
Explanation
During circular motion in a magnetic field, the angular frequency (ω) is given by the formula:ω = qB/mwhere:ω is the angular frequency,q is the charge of the particle,B is the magnetic field strength, andm is the mass of the particle.This formula shows that the angular frequency is directly proportional to the product of the charge and the magnetic field strength, and inversely proportional to the mass of the particle. It represents the rate of rotation or oscillation of the particle in the magnetic field. A higher charge or stronger magnetic field will result in a higher angular frequency, while a larger mass will lead to a lower angular frequency.

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.
