The energy is given in eV I checked two sources. But I got the correct answer with 2kev . Thank you very much for the hint.

[Moderator's note: Fixed a broken quote tag] Oo. Thank you. I got it de-broglie wavelength is h/ mv and v= √2E/m Putting the values I got the answer as 2.02*10^-11m . but the answer given is 6.4*10^-13 . I think I messed up somewhere. I want some help.thank you.

I'm Sarayu . I recently study at grade 12. I am really confused with lots of numericals and reasoning questions.so ; I would be very happy and thankfull to all friends helping me. Thank you.
