    Ram pushes the box by applying a force of 500 N in horizontal direction so that the box starts sliding-along the floor as shown in figure. Find the point where the frictional force acting on the box is maximum.

    A)  P                                            

    B)  Q                    

    C)  R                                

    D)  P, Q and R
