Practice question
Question
A container has whole blood (ρ\=1.06×103kg/m3) up to 1.5m. What is the gauge pressure at the bottom? (Take g\=9.8m/s2)
Explanation
Gauge pressure: Pg = ρgh. ρ = 1.06×103kg/m3, g = 9.8m/s2, h = 1.5m. Pg = 1.06×103×9.8×1.5 = 15582Pa. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 1.56 × 10⁴ Pa. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
