Under the influence of a uniform magnetic field a charged particle is moving in a circle of radius

R

with constant speed

v

. The time period of the motion:

Options

Adepends on both $R$ and $v$
Bis independent of both $R$ and $v$
Cdepends on $R$ and not on $v$
Ddepends on $v$ and not on $R$ .

Correct answer

B. is independent of both $R$ and $v$

Step-by-step solution

T=\frac{2 \pi m}{q B}

which is independent of both

R

and

V

.
