Consider the following statements about the blocks shown in the diagram that are being pushed by a constant force on a frictionless table:
(i) All block moves with the same acceleration
(ii) The forces acting on each block are the same
(i) Only
As we can see from the free body diagram, forces acting on each block is different. But, they will all move together as a system as same net force acts on them, and therefore they will have the same acceleration.
