SATHEE: Properties Of Solids And Liquids Question 271

Properties Of Solids And Liquids Question 271

Question: The fraction of a floating object of volume $V_{0}$ and density $d_{0}$ above the surface of a liquid of density d will be

Options:

A) $\frac{d_{0}}{d}$

B) $\frac{d d_{0}}{d + d_{0}}$

C) $\frac{d - d_{0}}{d}$

D) $\frac{d d_{0}}{d - d_{0}}$

Show Answer

Answer:

Correct Answer: C

Solution:

For the floatation $V_{0} d_{0} g = V_{i n} d g$

therefore $V_{i n} = V_{0} \frac{d_{0}}{d}$ $V_{o u t} = V_{0} - V_{i n} = V_{0} - V_{0} \frac{d_{0}}{d}$

$= V_{0} [\frac{d - d_{0}}{d}]$

therefore $\frac{V_{o u t}}{V_{0}} = \frac{d - d_{0}}{d} .$
