The kinetic energy of electron and proton is ${10}^{-32}\mathrm{J}\text{. }$ Then the relation between their de-Broglie wavelength is :

• A

  ${\lambda }_{\mathrm{p}}<{\lambda }_e$

• B

  ${\lambda }_{\mathrm{p}}>{\lambda }_{\mathrm{e}}$

• C

  ${\lambda }_{\mathrm{p}}={\lambda }_{\mathrm{e}}$

• D

  ${\lambda }_{\mathrm{p}}=2{\lambda }_{\mathrm{e}}$
