What is the effect on upthrust if the density of the liquid increases?
AUpthrust decreases
BUpthrust remains same
CUpthrust increases
DUpthrust becomes zero
✓ Correct Answer: C — Upthrust increases
Upthrust U = Vρg. Since upthrust is directly proportional to the density (ρ) of the liquid, increasing density increases upthrust.
