Two ions of masses $4 amu$ and $16 amu$ have charges $+ 2 e$ and $+ 3 e$ respectively. These ions pass through the region of the constant perpendicular magnetic field. The kinetic energy of both ions is the same. Then:

Options:

Answer:

Solution:

The relation between linear moment and radius in terms of the magnitude of magnetic field and charge of a particle, $r = \frac{P}{q B} = \frac{\sqrt{2 m k_{e}}}{q B}$

$\Rightarrow r \propto \frac{\sqrt{m}}{q}$ $\Rightarrow \frac{r_{1}}{r_{2}} = \frac{3}{4}$ $\Rightarrow r_{2} > r_{1}$ .
