Under the influence of a uniform magnetic field, a charged particle moves with constant speed

\mathrm{V}

in a circle of radius

R

. The time period of rotation of the particle :

Options

ADepends on both $v$ and $R$
BDepends on $v$ and not on $R$
CDepends on R and not on $v$
DIs independent of both $v$ and $R$

Correct answer

D. Is independent of both $v$ and $R$

Step-by-step solution

\mathrm{T}=\frac{2 \pi \mathrm{m}}{2 \mathrm{~B}}

\mathrm{T}

is time period
