Answer:
Balanced
Explanation:
The image below is balanced because the forces are oppositely directed and have equal magnitudes.
- Based on newtons first law of motion "a body will remain at rest or continue with uniform motion unless if it is acted upon by an external force".
- The external force creates an unbalanced force resolution on a body.
- For this body, a force of 5N acts to the left
- A force of 5N acts to the right
When forces are directed this way;
Resultant = 5N - 5N = 0N
A resultant force of 0N shows a balanced body.
