Two students are investigating the effect of forces on the motion of an object. The two students each push on a box, as shown in the picture.

Even though the students are pushing the box very hard, the box does not move. Which is the best explanation for why the box does not move?

• Student A is using more force than Student B.

• The force of friction from the floor surface is too great.

• All of the forces acting on the box are unbalanced.

• All of the forces acting on the box are balanced.
