An open pan P filled with water p (density ${\text{ρ}}_{\mathrm{w}}$) is placed on a vertical rod, maintaining equilibrium. A block of density $\mathrm{\rho }$ is placed on one side of the pan as shown. Water depth is more than height of the block.

• A

  Equilibrium will be maintained only if $\mathrm{\rho } < {\mathrm{\rho }}_{\mathrm{w}}$

• B

  Equilibrium will be maintained only if $\mathrm{\rho }\le {\mathrm{\rho }}_{\mathrm{w}}$

• C

  Equilibrium will be maintained for all relations between $\mathrm{\rho } \mathrm{and} {\mathrm{\rho }}_{\mathrm{w}.}$.

• D

  Equilibrium will not be maintained in all cases.
