Hydrogen ion and singly ionized helium atom are accelerated, from rest, through the same potential difference. The ratio of final speeds of hydrogen and helium ions is close to:

Options:

Answer:

Solution:

$qV = \frac{1}{2} {mv}^{2}$

Hence $v \propto \frac{1}{\sqrt{m}}$

$\frac{V_{H}}{V_{He}} = \sqrt{\frac{4}{1}} = 2 : 1$
