If an electron and a proton have the same de-Broglie wavelength, then the kinetic energy of the electron is
Text Solution
Verified by ExpertsThe correct answer is:
A
As the wavelength are the same,
.
Kinetic energy of the electron
Kinetic energy of the proton .
Therefore, the kinetic energy of electron is about 2000 times more than that of the proton, as the proton is about 2000 times heavier than the electron.
