Question

A metal sphere of volume V, having a cavity inside it, floats on water completely submerged. If the relative density of the metal is 1.5, the volume of the cavity is   

Solution

Correct option is

 

Let the mass of the sphere be m grams. Its volume is given to be V cm3. Since the sphere is completely submerged under water, volume of water displaced = Vcm3 = m cm3 since the density of water is 1 gcm–3. Since the density of the metal is 1.5 gcm–3, the volume of metal in the sphere is . Therefore, volume of cavity,
