Concept explainers
The ratio of kinetic energy of an electron to kinetic energy of a proton.
Answer to Problem 40P
Solution:
The ratio of kinetic energy of an electron to that of a proton is
Explanation of Solution
Given:
Wavelength of the electron and proton is equal.
Formula Used:
Calculation:
By using the formula
The ratio of kinetic energy of electron to that of protons is given as
……………………………………………………… (1)
Now, according to the formula
Wavelength for electron and proton can be given as
But the wavelength of the electron and proton is equal, that is
Now on substituting the value in equation (1), we get
The ratio of kinetic energy of an electron to that of a proton is .
