Under the influence of a uniform magnetic field, a charged particle moves with constant speed v in a circle of radius r. The time period of revolution of the particle

Options

A. depends on v and not on r
B. depends on r and not on v
C. is independent of both v and r
D. depends on both v and r

Answer

C

Explanation

The peroid of revolution `T = (2 pi m)/(q B)`. Thus, peroid of revolution in independent of both v and r.
