SUMMARY
The work done on a charge "q" of mass "m" by an electric field of magnitude "E" when moved a distance "d" is calculated using the formula W = qEd. This equation derives from the Lorentz force equation, where the force exerted by the electric field is F_e = qE. The mass of the charge is not required for this calculation, confirming that the work done is solely dependent on the charge, electric field strength, and distance moved.
