PhysicsHard145×since 2002Q6592A proton and an electron have the same de Broglie wavelength. If Kp\mathrm{K}_{\mathrm{p}}Kp and Ke\mathrm{K}_{\mathrm{e}}Ke be the kinetic energies of proton and electron respectively, then choose the correct relation :AKp>Ke\mathrm{K_p>K_e}Kp>KeBKp=Ke\mathrm{K_p=K_e}Kp=KeCKp<Ke\mathrm{K}_{\mathrm{p}}<\mathrm{K}_{\mathrm{e}}Kp<KeDKp=Ke2\mathrm{K}_{\mathrm{p}}=\mathrm{K}_{\mathrm{e}}{ }^2Kp=Ke2Check answerSkip
