Conclusion:
Substitute
Therefore, the energy released in the reaction is
(b)
Find the speed of proton and the electron after the reaction.
(b)
Answer to Problem 69CP
The speed of electron and the proton after the reaction are
Explanation of Solution
Consider that the neutron at rest then the momentum conservation for the decay process implies that,
Then, write the relativistic energy equation.
Here,
Since,
Write the equation for speed of electron.
Conclusion:
Substitute
Substitute
For finding the speed of proton replace mass of electron with mass of proton in equation IV.
Therefore, the speed of electron and the proton after the reaction is
(c)
Does any of these particle moving at a relativistic speed.
(c)
Answer to Problem 69CP
The electron is moving at relativistic speed whereas proton is not moving at relativistic speed.
Explanation of Solution
From the previous part the electron is moving at more than one tenth of
Whereas the speed of proton is less than one tenth of the speed of light so the proton is not moving with relativistic speed.

- Because the neutron has no charge, its mass must be found in some way other than by using a mass spectrometer.When a neutron and a proton meet (assume both to be almost stationary), they combine and form a deuteron, emitting a gamma ray whose energy is 2.2233 MeV.
