de Broglie wavelength of a particle moving with kinetic energy 2 MeV is 100 $\stackrel{\mathrm{o}}{\mathrm{A}}$. What is the de Broglie wavelength of a particle moving with kinetic energy 32 MeV?

• A

  $\raisebox{1ex}{$\lambda $}\!\left/ \!\raisebox{-1ex}{$\sqrt{2}$}\right.$

• B

  $2\lambda$

• C

  $\raisebox{1ex}{$\lambda $}\!\left/ \!\raisebox{-1ex}{$2$}\right.$

• D

  $\raisebox{1ex}{$\lambda $}\!\left/ \!\raisebox{-1ex}{$4$}\right.$
