A block of wood floats in water with (4 / 5) th of its volume submerged. If the same block just floats in a liquid, the density of the liquid is ( . in kgm ⁻³ )

Options

  1. A1250
  2. B600
  3. C400
  4. D800

Correct answer

D. 800

Step-by-step solution

Applying Archimedes' principle, submerged part = replaced water 4 5 h _ u s g=h _l g where, _w= density of water and _l= density of the liquid. array ll & _l= 4 5 _w= 4 5 1000 & _l=800 kgm ⁻³ array
