The 2.0 kg object (volume 4.0×10⁻³ m³) in water will
A.float, since its density (500 kg/m³) is below water's
B.sink, since its weight exceeds buoyancy
C.stay suspended at any depth
D.sink to the bottom instantly
Explanation
Core Concept
ρ = 2.0/(4.0×10⁻³) = 500 kg/m³ < 1000 kg/m³, so it floats.
Correct Answer
Afloat, since its density (500 kg/m³) is below water's
