Answer:
Figure (4)
Explanation:
In this case 4 free body diagrams are shown. In Figure (1), there is no normal force acting on the object. It will accelerate in downwards direction.
In figure (2), the box is balanced. All forces cancel out each other.
In figure (3), the box is not balanced. The horizontal forces cancel out each other while the downward force is greater than the greater than upward force. The object will accelerate in downward direction.
In figure (4), no normal force is acting. In this case, the force towards right is more than the force towards left. So, the object will move towards right.
Hence, the correct option is (c) " figure (4) only".
