A cylinder is filled with a non-viscous liquid of density d to height ho and a hole is made at a height h 1 from the bottom of the cylinder. The velocity of the liquid coming out of the
hole is:

• A

  $\sqrt{2{\mathrm{h}}_0\mathrm{g}}$

• B

  $\sqrt{2\mathrm{g}({\mathrm{h}}_0-{\mathrm{h}}_1)}$

• C

  $\sqrt{{\mathrm{gdh}}_1}$

• D

  $\sqrt{{\mathrm{dgh}}_0}$
