Question:
An object is put one by one in three liquids having different densities. The object floats with $1 / 9,2 / 11$ and $3 / 7$ parts of their volumes outside the liquid surface in liquids of densities $d_{1}, d_{2}$ and $d_{3}$ respectively. Which of the following statement is correct?
(a) $d_{1}>d_{2}>d_{3}$
(b) $d_{1}>d_{2} (c) $d_{1} (d) $d_{1}
Solution:
(d). Upthrust due to liquid on an object is directly proportional to the density of the liquid.
