Answer:
False statement.
Step-by-step explanation:
It is given that,
Force with which a man pulls a box, F = 50 N (one side)
Force with which pushes on the box, F' = 60 N (in opposite direction)
The forces acting on the box are unbalanced. It means that the force acting in one side is more or less then force in other side. As a result the box will move.
So, the given statement is false.
