Gravitational field strength g = weight / mass Steps:

• Use formula g = W / m to find field strength for each object.
• For A: g = 125 N / 15 kg ≈ 8.33 m/s².
• For B: g = 180 N / 20 kg = 9 m/s².
• For C and D: g = 225 N / 25 kg = 9 m/s² each. Why A is correct:
• Lowest g value (8.33 m/s²) from W / m formula, indicating weakest gravitational pull per Newton's law. Why the others are wrong:
• B: g = 9 m/s², higher than A.
• C: g = 9 m/s², higher than A.
• D: g = 9 m/s², higher than A (identical to C, violating "different masses" but still not smallest).

Final answer: A
