Concept explainers
To Calculate: Potential difference to accelerate an electron.
Answer to Problem 27PP
Explanation of Solution
Given data:
Wavelength of electron,
Formula used:
de Broglie wavelength of electron is related to its velocity:
Here, h is the Planck’s constant, m is the mass of electron and v is the velocity of the electron.
The potential difference V can be obtained by:
Calculation:
The velocity of the electron can be obtained using the de Broglie wavelength.
Conclusion:
The potential difference to accelerate an electron is
