The potential difference \(V\) required for accelerating an electron to have the de-Broglie wavelength of \(1 Å\) is
- A \(100 \mathrm{V}\)
- B \(125 \mathrm{V}\)
- C \(150 \mathrm{V}\)
- D \(200 \mathrm{V}\)
Answer & Solution
Correct Answer
(C) \(150 \mathrm{V}\)
Step-by-step Solution
Detailed explanation
The de-Broglie wavelength associated with electron is given by. \[ \lambda=\frac{h}{\sqrt{2 m e V}} \] where, \(h=\) Planck's constant…
