A stream of electrons from a heated filament was passed between two charged plates kept at a potential difference $\displaystyle V$ esu. If $\displaystyle e$ and $\displaystyle m$ are charge and mass of an electron, respectively, then the value of $\displaystyle h / \lambda$ (where $\displaystyle \lambda$ is wavelength associated with electron wave) is given by :
Official answer
(4)
$\displaystyle \sqrt{2 m e V}$
