A ball of density $\mathrm{\rho }$ is  gently released in a liquid of density o where $\rho$ > o. What will be the acceleration of the free fall of the ball in the liquid ?

• A

  g

• B

  $(\mathrm{\rho }-\mathrm{\sigma })\mathrm{g}$

• C

  $(\mathrm{\rho }-\mathrm{\sigma })\mathrm{g}/\mathrm{\rho }$

• D

  $\mathrm{\rho g}/(\mathrm{\rho }-\mathrm{\sigma })$
