Explanation:

To solve this, we analyze the forces (assuming the diagram has upward/downward or horizontal forces, but from the given 200N and typical force diagrams, let's assume vertical forces: say upward force is 70N and downward is 200N? Wait, no—wait, the diagram shows a 200N force, maybe horizontal? Wait, no, the options are net force downward 130, upward 270, balanced, net zero, unbalanced. Wait, maybe the diagram has two forces: upward (e.g., 70N) and downward (200N)? Wait, no—wait, maybe the forces are: let's assume the object has a downward force of 200N and an upward force of 70N? Then net force is 200 - 70 = 130N downward. And unbalanced force (since net force is not zero). Wait, but the options: "net force = 130 N downward" and "unbalanced force" would be true. But wait, maybe the diagram has upward force 270N and downward 200N? No, the 200N is on the object. Wait, maybe the forces are: upward 70N and downward 200N: net force = 200 - 70 = 130N downward (unbalanced, since net force ≠ 0). So:

• "net force = 130 N downward" is true (if downward force is 200N, upward is 70N: 200 - 70 = 130N downward).
• "unbalanced force" is true (since net force ≠ 0).

But wait, the options: let's re-examine. The options are:

1. net force = 130 N downward
2. net force = 270 N upward
3. balanced force
4. net force equals zero, no movement
5. unbalanced force

Assuming the diagram has a downward force of 200N and an upward force of 70N (or vice versa, but net force downward 130). So:

• Net force: 200 - 70 = 130N downward (so option 1 is true).
• Unbalanced force: since net force ≠ 0, option 5 is true.

But maybe the diagram has upward 270N and downward 200N: net force 70N upward, but that's not an option. Wait, maybe the forces are horizontal: left force 70N, right force 200N: net force 130N right, but options are downward/upward. Wait, maybe the diagram is vertical: weight (downward) 200N, and upward force 70N: net force 130N downward (unbalanced). So the true statements are "net force = 130 N downward" and "unbalanced force".

But let's check the options again. The problem says "select the statement(s) that are true". So:

• "net force = 130 N downward": True (if downward force is 200N, upward is 70N: 200 - 70 = 130N downward).
• "unbalanced force": True (since net force ≠ 0, so forces are unbalanced).

The other options:

• "net force = 270 N upward": False (200 + 70 = 270, but that's if forces are in same direction, but net force is sum, but usually forces are opposite).
• "balanced force": False (net force ≠ 0).
• "net force equals zero, no movement": False (net force ≠ 0).

So the true statements are:

• net force = 130 N downward
• unbalanced force

But the problem might have a diagram where upward force is 70N and downward is 200N. So the answers are those two. But let's confirm.

1. net force = 130 N downward: If the downward force is 200N and upward force is 70N, net force = \( 200 - 70 = 130 \, \text{N} \) downward.
2. unbalanced force: Since net force \(

eq 0 \), the forces are unbalanced (balanced forces have net force = 0).

Answer:

• net force = 130 N downward
• unbalanced force
