Question

A charged particle is moving on a circular path in transverse magnetic field. The time period for the circular path will not depend on-

• A. Magneitc field
• B. Charge of the particle
• C. Mass of the particle
• D. Velocity of the particle

Answer 1

The correct option is D Velocity of the particle

$BqV=mvr⟹r=\frac{Bq}{m}⟹kT=\frac{Bq}{m}$ Since($r\alpha t$)

$\therefore$ Time period is independent of velocity $\overrightarrow{v}$.
