A leak proof cylinder of length , made of a metal which has very low coefficient of expansion is floating vertically in water at such that its height above the water surface is . When the temperature of water is increased to , the height of the cylinder above the water surface becomes The density of water at relative to the density at is close to :
Option: 1 1.03
Option: 2 1.01
Option: 3 1.26
Option: 4 1.04
As
Buoyant force-
The buoyant force is given as
Where FB=Buoyant force
= density of the fluid
V= Volume of the solid body immersed in the liquid or Volume of the fluid displaced
So
So the correct option is 2.
