Question

Comprehension (Numerical 5-41 to 5-43): a large tank of cross-section $A$ holds liquid of density $ρ$ . A cylinder of density $ρ /4$ , length $l$ and cross-section $a ≪ A$ is held just submerged by an external downward force (Figure 5.117). At $t = 0$ the force is removed. The water level is constant. The acceleration of the cylinder just after the force is removed is:
