QNEET-2024-Ph-170: NEET 2024 Physics - Class 12 NEET-2024-Ph-170 Solution: An electron and an alpha particle are accelerated by the same…
An electron and an alpha particle are accelerated by the same potential difference. Let and denote the de-Broglie wavelengths of the electron and the alpha particle respectively then:
Multiple Choice Options
- A \lambda_e>\lambda_\alpha _ e _ > _ _ _
- B _ e _ = 4 _ _ _
- C _ e _ = _ _ _
- D \lambda_e<\lambda_\alpha _ e _ < _ _ _
Step-by-Step Verified Solution
de-Broglie wavelength is given by
_ = h p = h 2 m q V
For same potential difference
_ _ 1 m q _ _ _ e = m e q e m _ q _ _ m _ _ m e _ e > _ _
