SOLVE PROBLEM:

In this example, does this represent balanced or unbalanced? What is the Net Force for this problem?

• Balanced force & net force is 130 N to the right

• Unbalanced force & net force is 130 N to the left

• Balanced force & net force is 30 N to the right

• Unbalanced force & net force is 30 N to the right
