The frequency of circular motion for a charged particle moving around in the presence of a uniform magnetic field does not depend on ...
The radius of the circle
The mass of the particle
The charge of the particle
The magnitude of the magnetic field
Actually, it depends on all of the above quantities
Are we supposed to pick one?
The so-called cyclotron frequency of a charged particle in a magnetic field is proportional to B q/m. See

One of the first four choices is correct.
To determine which option the frequency of circular motion for a charged particle moving around in a uniform magnetic field does not depend on, we need to understand the relevant physics concept.
When a charged particle moves perpendicular to a magnetic field, it experiences a force called the Lorentz force, which causes it to move in a circular path. The frequency of circular motion refers to how many complete revolutions the particle makes in a given time.
The frequency of circular motion can be determined using the following equation:
f = qB / (2πm)
Where:
f is the frequency of circular motion
q is the charge of the particle
B is the magnitude of the magnetic field
m is the mass of the particle
From this equation, we can see that the frequency (f) depends on the charge of the particle (q), the magnitude of the magnetic field (B), and the mass of the particle (m). The radius of the circle is not directly involved in the equation.
Therefore, the correct answer is: The frequency of circular motion for a charged particle moving around in the presence of a uniform magnetic field does not depend on the radius of the circle.
