Question

For a charged particle of charge $q$ and mass $m$ undergoing uniform circular motion in a uniform perpendicular magnetic field $B$ with a speed $v$, the angular frequency of the charged particle is independent of

​​​​​​​$[$0.77 Mark$]$

• A. Mass
• B. Speed
• C. Charge
• D. Magnetic field

Answer 1

The correct option is B Speed

For a charged particle of charge $q$ and mass $m$ undergoing uniform circular motion in a uniform perpendicular magnetic field $B$ is given by,

$T=\frac{2\pi m}{qB}$

Angular frequency, $\omega =\frac{2\pi }{T}=\frac{qB}{m}$

Thus, it is independent of the speed of the particle.
