A thin uniform cylindrical shell, closed at both ends, is partially filled with water. It is floating vertically in water in half-submerged state. If ρc is the relative density of the material of the shell with respect to water, then the correct statement is that the shell is [Main 2012- II]
a. more than half-filled if ρc is less than 0.5.
b. more than half-filled if ρc is more than 1.0.
c. half-filled if ρc is more than 0.5.
d. less than half-filled if ρc is less than 0.5.
