A stream of electrons from a heated filament was passed between two charged plates kept at a pot....

A stream of electrons from a heated filament was passed between two charged plates kept at a potential \( \mathrm{P} \) difference \( \mathrm{V} \) esu. If \( \mathrm{e} \) and \( \mathrm{m} \) are charge and mass of an electron, respectively, then the value of \( \mathrm{h} / \lambda \) (where \( \lambda \) is wavelength associated with electron wave) is given by: (1) \( \sqrt{2 \mathrm{meV}} \) (2) \( \mathrm{meV} \) (3) \( 2 \mathrm{meV} \) (4) \( \sqrt{\mathrm{meV}} \) 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
