Determine the ratio of the electrons speed to speed of light

Reference no: EM13982398

An electron is accelerated through some potential difference to a final kinetic energy of 1.95 MeV. Using special relativity, determine the ratio of the electron's speed v to the speed of light c. What value would you obtain for this ratio if instead you used the classical expression for kinetic energy?
