Practice question

Total pressure: P = Pa+ρgh. Pa = 1.01×105Pa, ρ = 1000kg/m3, g = 9.8m/s2, h = 3.2m. P = 1.01×105+1000×9.8×3.2 = 1.01×105+31360 = 1.3236×105Pa. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 1.32 × 10⁵ Pa. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
