MCQ
If a proton and electron have same de Broglie wavelength, then:
  • A
    Kinetic energy of electron $<$ kinetic energy of proton
  • B
    Kinetic energy of electron $=$ kinetic energy of proton
  • ✓
    Momentum of electron $=$ momentum of proton
  • D
    Momentum of electron $<$ momentum of proton
✓

Answer

Correct option: C.
Momentum of electron $=$ momentum of proton

If proton and electron have same debroglie wavelength then momentum of electron is equals to momentum of proton.
