A body of density $\rho'$  is dropped from rest at a height $h$ into a lake of density $\rho$ , where $\rho > \rho '$ . Neglecting all dissipative forces, calculate the maximum depth to which the body sinks before returning to float on the surface.
  • A$\frac{h}{{\rho \,\, - \,\,\rho '}}$
  • B$\frac{{h\,\rho '}}{\rho }$
  • C$\frac{{h\,\rho '}}{{\rho \,\, - \,\,\rho '}}$
  • D$\frac{{h\,\rho }}{{\rho \,\, - \,\,\rho '}}$
