A cubical block \( (a \times a \times a) \), with a coin of mass
' \( m \) ' over it is floating over a liquid of density \( \rho \).
\( \mathrm{P} \)
In this case \( \mathrm{x}_{1} \) depth of the block is immersed.
W
Now the coin is removed \& it is found that \( \mathrm{x}_{2} \)
depth is immersed in liquid. Value of \( \left(\mathrm{x}_{1}-\mathrm{x}_{2}\right) \) is
(1) \( \frac{m}{\rho a^{2}} \)
(2) \( \frac{\rho a^{4}}{m} \).
(3) \( \frac{m}{2 \rho a^{2}} \)
(4) data insufficient
