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 massof proton to be 1837 times larger than the mass of electron

V volt

1837 V volt

`V//`1837 volt

`sqrt( 1837)` V volt
