Question

an object is put one by one in free liquid having different densities the object floats with 1/9,2/11,and 3/7parts of their volumes outside the liquid surface in liquids of densities d1 ,d2 and d3 respectively , which of the following statement is correct.
​

Answer 1

Answer:

Buoyant Force is when a rigid object is submerged in a fluid (completely or partially), there exits an upward force on the object that is equal to the weight of the fluid that is displaced by the object.

In this case, there are 3 liquids with varying densities.91 =0.11, 112 =0.18and 73 =0.43. These are the volume outside of liquids of densities d 1 ,d 2 and d e  respectively. This means that the buoyant force is maximum for d 3  and minimum for d 1. As the buoyant force is proportional to density, the densities of the liquids are in the order d 1 <d 2 <d 3 .
