Equilibrium of forces on a kite Steps:

• Weight W acts vertically downward due to gravity.
• Tension T acts along the string, upward and toward the holder at an angle.
• Wind force F provides lift (upward) and drag (horizontal), opposing T's horizontal component.
• In equilibrium, the three forces form a closed vector triangle where W + T + F = 0.

Why A is correct:

• Newton's first law requires the vector sum of forces to be zero; diagram A shows T, W, and F head-to-tail forming a closed triangle.

Why the others are wrong:

• B: Vectors do not close, implying net force and acceleration.
• C: Incorrect directions; F shown downward, unbalancing vertical components.
• D: Open polygon violates equilibrium condition.

Final answer: A
