Answer :
- The ratio of densities of two liquids is 1 : 2
Given :
- A cube of side 4cm is just completely immersed I liquid A. When it is put in liquid B , it floats with 2cm outside the liquid
To find :
- Calculate the ratio of densities of two liquids
Solution :
Given
- A cube of side 4cm is just completely immersed I liquid A.
- When it is put in liquid B
- It floats with 2cm outside the liquid so,
- Mass of cube = Mass of liquids
As we know that,
- m = pA/pB
where,
- pA is 2cm
- pB is 4cm
Which is liquid A and Liquid B
⤍ M = pA/pB
⤍ 2/4
⤍ 1 : 2
Hence , The ratio of densities of two liquids is 1 : 2
