Final answer:
The normal force does not do any work on a laptop moving horizontally, as the force is perpendicular to the motion and there is no displacement in the direction of the normal force.
Step-by-step explanation:
The amount of work done by the normal force on an object moving horizontally is typically zero. This is because the normal force acts perpendicular to the direction of the object's displacement. In the case of the laptop moving 2.0 m horizontally, the normal force does not do any work on the laptop because there is no displacement in the direction of the normal force.
