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?

Solutions

Expert Solution

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.

------------

Inner Diameter,
