SUMMARY
The electric potential energy of a charge \( q \) in an electric field is defined as the work done by an external force in moving the charge from infinity to a specific point in the field without any acceleration. This definition emphasizes that the charge must not experience any change in kinetic energy during the process, ensuring that the work done directly translates to a change in potential energy. The discussion clarifies that any acceleration would alter the kinetic energy, complicating the relationship between work and potential energy.
