SUMMARY
Electrons accelerated to a kinetic energy of 109 eV exhibit significant relativistic effects. The mass ratio of these electrons to their rest mass is calculated using the formula m = m0 / √(1 - (v²/c²)), where m0 is the rest mass. Their velocity approaches the speed of light (c = 3 x 108 m/s), resulting in a velocity ratio of approximately 0.9995. The total energy ratio to rest mass energy is determined using E = m0c², yielding a ratio of about 1,000,000.
