Final answer:
The work done by the electric field on a charge cannot be calculated without additional details such as electric field strength and distance between the points. Normally, work is computed using the charge, electric field, and distance along the field's direction.
Step-by-step explanation:
To calculate the work done by the electric field on a charge moving between two points, we use the formula: W = qEd, where W is work, q is the charge, E is the electric field strength, and d is the distance between the points. However, we require additional information such as the strength and direction of the electric field, along with the distance traveled by the charge from point B to point A. Unfortunately, with the information provided, it is not possible to calculate the work done. Typically, if the electric field E and distance d are known and if the motion is along the direction of the field, we multiply the charge (2.60 nC = 2.60 × 10-9 C) by the electric field and the distance to get the work done.
