In capillary tube having area of cross-section ' A ', water rises to a height ' h '. If cross sectional area is reduced to A 9 , the rise of water in the capillary tube is

Options

  1. Ah
  2. B4 h
  3. C3 h
  4. D2h

Correct answer

C. 3 h

Step-by-step solution

aligned & h= 2 T r g & h 1 r & And A= r^2 r A & h 1 A & Now, h₂ h₁ = A₁ A₂ & h₂ h = A A / 9 =3 & h₂=3 h aligned
