To solve the question, we need to define the concept of work done per unit charge when moving a charge from one point to another in an electric field. ### Step-by-Step Solution: 1. **Understanding the Concept**: - When a charge is moved from point A to point B in an electric field, work is done on the charge. This work is related to the electric potential at points A and B. 2. **Definition of Work Done**: ...
