Question

Each of the pictures shows four objects tied together with rubber bands being pulled to the right across a horizontal frictionless surface by a force $F$ . All the objects have the same mass. All the rubber bands obey Hooke’s law and have the same equilibrium length and the same force constant. Which of the pictures is drawn most correctly?
