Describe an example where you want to solve for a balanced Fnet = 0N

An unopened door pushed by two people with same force is the example for balanced Fnet=0N

Explanation:

There are two types of forces that acts on an object.

Balanced force and unbalanced force

In balanced force the net force becomes zero as the name itself indicates that the forces acting on the object gets balanced and cancels out each other.

Example: - Consider a door, and if two people with equal forces are trying to push the door. Then the net force becomes zero as the door remains not opened.

In unbalanced force the net force will not be zero as the forces acting on them are not equal.

Example: Soccer game ball pushed by the player is the best example.
