Questions  

A particle of charge q and mass m moves in a circular orbit of radius r with angular speed ω. The ratio of the magnitude of its magnetic moment to that of its angular momentum depends on

a
ω  and  q
b
ω  q and  m
c
q and m
d
ω  and  m

detailed solution

Correct option is C

The effective current, i=qω2π  and  A=πr2Magnetic moment, M=iA =12  qωr2Angular moment, L=Iω =mr2 ω  ⇒  ML  =  q2m
