Question

A solid of density 900 kg/m per cube floats in oil . The oil floats on water of density 1000 kg /m per cube . The density of oil in kg/m per cube could be

Answer 1

Answer:

the density of oil could be between 900-1000kg/cubic metre

Explanation:

Answer 2

Answer:

$\huge\bold\blue{\underline{\underline{\mathcal{Given:}}}}$

Density of cube = 900kg/m

Density of water = 1000kg/m

Cube floats on water

=> density of cube < density of oil

Oil floats on water

=> density of oil < density of water

$\huge\bold\pink{\underline{\underline{\mathcal{To\:find:}}}}$

Density of oil?

$\huge\bold\green{\underline{\underline{\mathcal{solution:}}}}$

Cube floats on water

Cube floats on water=> density of cube < density of oil

=> 900kg/m < density of oil - i

Oil floats on water

Oil floats on water=> density of oil < density of water

=> density of oil < 1000kg/m - ii

From i and ii

900 < density of oil < 1000

=> density of oil = 900 +{1000 - 900/2p

= 900 + (100/2)

Density of oil = 950 kg/m
