Current Loop as a Magnetic Dipole

Let the current ' II ' be associated with an electron of charge ' ee ' moving in a circular orbit of radius ' rr ' with speed ' vv ' around the positively charged nucleus. The ratio rv\frac{r}{v} is

Show answer and solution

Answer: (c)

  1. I=eT=ev2πrI = \frac{e}{T} = \frac{ev}{2\pi r}
  2. rv=e2πI\frac{r}{v} = \frac{e}{2\pi I}, so the answer is (c).
