Two liquids L1 and L2 are contained in a U – tube. The height and the density of L1 are 8 cm and 10³ kgm−³ respectively. If the density of L2 is 800 kgm−³, its height measured from the same level is
A. 8 cm B. 10 cm C. 16 cm D. 12 cm Correct Answer: Option B = 10 cm Explanation Generally, from Hares Experiment, density is inversely proportional to height i.e h ∝1/d; → h1d1 = h2d2 ∴ 8 x 10³ = h2 x 800 ∴ h2 = 8 x 10³/800 =...
