SUMMARY
The force on an electron between two parallel plates separated by 10.0 cm with a potential difference of 500.0 V is calculated using the formula F = Vq / r. The correct calculation yields a force of 8 x 10-18 N, not 8 x 10-16 N as initially computed. The error in the initial calculation stemmed from a miscalculation of the electron charge and the distance between the plates.
