PhysicsEasysingle choice

Three ions $H^{+}, H e^{+} {and O}^{+ 2}$ having the same kinetic energy pass through a region in which there is a uniform magnetic field perpendicular to their velocity, then

Options:

Answer:

Solution:

$r = \frac{\sqrt{2 m E}}{q B} \Rightarrow r \propto \frac{\sqrt{m}}{q} \Rightarrow r_{H^{+}} {: r}_{{He}^{+}} : r_{O^{+ 2}} = \frac{\sqrt{1}}{1} : \frac{\sqrt{4}}{1} : \frac{\sqrt{16}}{2} = 1 : 2 : 2$
