An electron accelerated through a potential difference of V volt has a wavelength `lambda` associated with it. Mass of proton is nearly 2000 times that of an electron .In order to have the same `lambda` for proton, it must be accelerated through a potential difference (in volt) of

A

100 V

B

2000 V

C

`V//2000`

D

`sqrt(2000)`
