# Find the Compression -2!

A cubical block of volume $$V$$ and density $$3\rho$$ is placed inside a liquid of density $$\rho$$ and attached to a spring of spring constant $$k$$ as shown in the figure. Assuming ideal spring and pulley and spring is attached at $$A$$ which is at $$\frac{R}{2}$$ from center. The compression in the spring at equilibrium is:
