An electron is accelerated through a potential difference of V volt. It has a wavelength \[\lambda \] associated with it. Through what potential difference an electron must be accelerated so that its de Broglie wavelength is the same as that of a Proton? Take mass of proton to be 1837 times larger than the mass of electron.

• A. \[Vvolt\]
• B. \[1837V\,volt\]
• C. \[V/1837\,volt\]
• D. \[\sqrt{1837}V\,volt\]
