To move a refrigerator, forces are applied as shown. Which of these statements best describes what will happen if the forces are applied at exactly the same time?

• The refrigerator will move left because of the greatest force on the right.

• The refrigerator will move right because the force is over a greater surface area.

• The refrigerator will remain in place because the forces are not enough to move a refrigerator.

• The refrigerator will remain in the same place because the net force is zero.
