A hollow spherical metal shell of density 6.90 g/cm3 floats almost completely submerged in water. If the outer diameter of the metal shell is 14.0 cm, what is the inner diameter?
Consider the hollow spherical metal shell
Weight of the spherical metal shell is acting downwards
Which is balanced by the buoyant force acting upwards
The buoyant force is equal to the density of the fluid * volume of fluid displaced * g
Since the sphere is completely submerged, the volume of fluid displaced is equal to the outer volume of the sphere.
