Two identically charged particles A and B initially at rest, are accelerated by a common potential difference V. They enters into a transverse uniform magnetic field B. They describe a circular path of radii $r_1$and $r_2$ respectively then their mass ratio is :

Question

( B ) $(\frac{r_2}{r_1})$
( C ) $(\frac{r_2}{r_1})^{2}$
( D ) $(\frac{r_1}{r_2})$
