Question
A rectangular block is slowly pushed face-down into a liquid. The block has height d. The cross-sectional area of the block A = 5cm2 The figure shows the apparent weight (Wapp ) of the block as a function of depth h of its lower face, then the density of liquid is (g=10m/s2 )
- 103 Kg/m3
- 2 × 103 Kg/m3
- 0.5 × 103 Kg/m3
- 1.5 × 103 Kg/m3
The correct answer is: 2 × 103 Kg/m3

A cylindrical block of density d stays fully immersed in a beaker filled with two immiscible liquids of different densities d1 and d2 . The block is in equilibrium with half of it in liquid 1 and the other half in liquid 2, as shown in the figure. If the block is given a small displacement downward and released, then neglecting frictional losses
i) it executes simple harmonic motion
ii) its motion is periodic but not simple harmonic
iii) the frequency of oscillation is independent of the size of the cylinder
iv) the displacement of the centre of the cylinder is symmetric about its equilibrium position
