Total downward force includes weight plus rain force Steps:

• Compute rain force: pressure × area = 4 N/m² × 2 m² = 8 N downward.
• Add to weight: 60 N + 8 N = 68 N total downward force on table.
• Table exerts equal upward reaction on ground: 68 N downward by Newton's third law. Why D is correct:
• Force on ground equals net downward force per equilibrium and third law, with rain force F = P × A = 8 N added to weight. Why the others are wrong:
• A subtracts rain force (60 N - 8 N), but rain adds downward force.
• B subtracts a miscalculated smaller force (60 N - 2 N), ignoring addition.
• C adds too little (60 N + 2 N), likely from incorrect P × A (e.g., using 1 N/m²).

Final answer: D
