Question
The work done by rod against buoyant fore until rod sinks completely(A) $\rho_{w} A l^{2} g$(B) $\frac{\rho_{w} A l^{2} g}{2}$(C) $2 \rho_{w} A l^{2} g$(D) Zero
Step 1
The rod remains in a vertical position in both air and water, and the water level remains unchanged due to the rod. The velocity of the rod in the air and the water remains constant. Show more…

The average body and force until rod sinks completely (A) $2 \rho_{w} \lg A$ (B) $\frac{\rho_{w} \lg A}{2}$ (C) $\rho_{w} \lg A$ (D) $\frac{\rho_{w} l A g}{3}$
A cubical block of wooden edge $l$ and a density $\rho$ floats in water of density $2 \rho$. The lower surface of eube just touches the free end of a massless spring of force constant $k$ fixed at the bottom of the vessel. The weight $w$ put over the block so that it is completely immersed in water without wetting the weight is (a) $a(l \rho g+k)$ (b) $a(f \rho g+k)$ (c) $a\left(\frac{l \rho g}{2}+2 k\right)$ (d) $l\left(F_{p g}+\frac{k}{2}\right)$
