प्रश्न
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 d1, d2 and d3 respectively. Which of the following statement is correct?
पर्याय
d1 > d2 > d3
d1 > d2 < d3
d1 < d2 > d3
d1 < d2 < d3
उत्तर
d1 < d2 < d3
Explanation:
When an object floats in liquid, a buoyant force acts on it, which is equal to the weight of the liquid displaced by that object. As more part of object’s volume floats outside the liq^O&ftore is the buoyant force and higher is the density of the liquid.
