SUMMARY
The discussion focuses on calculating the potential difference required to accelerate an electron from rest to a speed of 0.99c. The relevant equation used is E=γmc²=V*q, where γ represents the Lorentz factor. The initial calculation yielded 3.63e6 eV, but the correct potential difference is 3.1e6 V. The confusion arose from the relationship between energy in electronvolts (eV) and volts (V), clarified by the equation Vg=mc²(γ-1).
