Balanced & Unbalanced

This free body diagram shows a balanced object. In other words this object is being pulled and pushes with the same force. How do I know. Well if you see in the diagram both sides  left to right have both with 5n forces. Which means that the object is balanced. 

In this free body diagram the objects are being pulled with different forces. Which means that the object doesn't have a balanced force. So it's unbalanced. This means that the object is being pulled with a string downwards. Because as you can see  the normal force is 600N and the gravational force is 800N which shows that the force isn't balanced because 800 is greater than 600  newtons.
