(2) No, force has to be applied in order to displace the box.
(3) If force applied to both the boxes is same, then empty box will be displaced more than box with books.
(4) If the same force is applied for a heavier load then the displacement will be less.
(5) Whatever be the amount of force applied, the wall will not be displaced.
(6) If no displacement occurs, then no work is said to be performed.
