In an electron gun, the electrons are accelerated by a potential $V$ . If $e$ is the charge and $m$ is the mass of an electron, then the maximum velocity of these electrons will be

Options:

Answer:

Solution:

$eV = \frac{1}{2} {mv}^{2} \Rightarrow v^{2} = \frac{2 eV}{m} \Rightarrow v = \sqrt{\frac{2 eV}{m}}$
