Question

A vessel contains oil (density=0.8 gm/cm3) over mercury (density=13.6gm/cm3) . A homogeneous sphere floats with half of its volume immersed in mercury and the other half in oil. The density of the material of the sphere in gm/cm3 is

Answer 1

0.8/2+13.6/2=0.4+6.8=7.2gm/cm3

Answer 2

Answer:

7.2gm/cm^3

Explanation:

Bouyant force =V×d

Let the volume of the sphere be V.

Therefore,

Volume in oil=V/2

Bouyant force in oil =Vd/2

=V(0.8)/2=>0.4V

Similarly,

Volume in mercury=V/2

Bouyant force in mercury = Vd/2

=V(13.6)/2=>6.8V

Total bouyant force=0.4V+6.8V

=7.2V

As,

Bouyant force =V×d

We can get;

7.2V=V×d

Therefore,

7.2=d
