De brogli wavelength of e and proton are equal. Then ratio of K.E. of electron and proton is?

An electron and a proton each have a thermal kinetic energy of3kBT/2. Calculate the de Broglie wavelength of each particle at atemperature of 2040 K. (kB is Boltzmann's constant, 1.38×10-23 J/K.The mass of the electron is 9.11×10-31 kg and the mass of theproton is 1.67×10-27 kg.)
Wavelength of the electron =
Wavelength of the proton =

An electron and a proton both moving at non relativistic speedshave the same de broglie wavelength. Which of the following arealso the same for the two particles?

i-speed
ii-kinetic energy
iii-momentum
iv-frequency
