The de Broglie wavelength associated with a proton under the influence of an electric potential of volts is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
From the conservation of energy, 12mv2=eV ⇒p22m=eV ⇒p2=2meV ⇒p=2meV Wavelength, λ=hp ⇒λ=h2meV ⇒λ=6.625×10-342×1.67×10-27×1.6×10-19×100…
