A body of volume v and density p is initially suberged in a liquid of density o. It is lifted through a height h in the liquid. Its potential energy

• A

  $\text{ increase by }\mathrm{hv}(\mathrm{\rho }-\mathrm{\sigma })\mathrm{g}$

• B

  $\text{ decrease by hv(ρ−σ)g}$

• C

  $\text{ increase by }(\mathrm{hv\rho g}/\mathrm{\sigma })$

• D

  $\text{ decrease by }(\mathrm{hv\rho g}/\mathrm{\sigma })$
