Question

Water and mercury are filled in two cylindrical vessels up to same height. Both vessels have a hole in the wall near the bottom. The velocity of water and mercury coming out of the holes are v₁ and v₂ respectively.

विकल्प

• v₁ = v₂

•  v₁ = 13.6 v₂

• v₁ = v₂/13.6

• \[\text{v}_1 = \sqrt{13 . 6} \text{v}_2\]

   

Answer 1

v₁ = v₂

The velocity of efflux does not depend on the density of the liquid. It only depends on the height h (given same in the question) and acceleration due to gravity g (constant value here).
v₁ = v₂ = v = `sqrt(2"gh")`
