SUMMARY
The final speed of an electron, starting from rest and passing between two parallel plates with a potential difference of 5000V, is calculated using the formula v=sqrt(2qV/m). With the charge of the electron (q) at 1.6*10^-19C and its mass (m) at 9.1*10^-31kg, the resulting speed is 4.2*10^7 m/s. While this calculation is valid under Classical Physics, it does not account for relativistic effects at higher potential differences, such as 30,000V, where the electron's speed would exceed the speed of light, violating physical laws.
