Problem
Two identical point charges of +5μC are fixed 0.25m apart. A third charge of −5μC is slowly brought in from infinity and placed at the midpoint between the positives. Indicate whether the external agent does positive work, negative work, or zero work during this process, and explain your reasoning in one or two sentences.
