1. Given: The charge on the electron is
qe = 1.60218 *10 ^-19 C.
Given: The mass of the electron is
me = 9.10939 * 10 ^-31 kg.

What is an electron's momentum, if it is
accelerated across a 6 mm potential difference
of 220 kV? Answer in units of keV/c.

2. Determine the energy required to accelerate
an electron from 0.587 c to 0.65 c . Answer in
units of MeV.

Solution Summary

I have found the relativistic momentum of an electron upon acceleration through a large potential difference. I also have found the change in its total relativistic energy. This is a classic problem encountered often in special theory of relativity.
