a box sitting on a bench could produce this force diagram. which statement is not correct? the normal force and the weight are balanced; there is no vertical acceleration. fn is the normal force and the force exerted by the bench on the box. there are no forces acting in the x - direction; the velocity in the x - direction is zero.

a box sitting on a bench could produce this force diagram. which statement is not correct? the normal force and the weight are balanced; there is no vertical acceleration. fn is the normal force and the force exerted by the bench on the box. there are no forces acting in the x - direction; the velocity in the x - direction is zero.

Answer

Brief Explanations:

  1. Analyze the vertical - force situation: For a box sitting on a bench, the normal force (F_N) exerted by the bench on the box and the weight (mg) of the box are balanced since the box is at rest vertically ((a_y = 0)). So the first two statements are correct.
  2. Analyze the horizontal - force situation: Since no horizontal forces are shown in the diagram and the box is at rest on the bench, there are no forces acting in the x - direction and the velocity in the x - direction is zero. All the given statements are correct. There seems to be an error in the problem setup as no incorrect statement is present among the options.

Answer:

There is no incorrect statement among the given options.
