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
- Ah
- B4 h
- C3 ~h
- D2 ~h
Correct answer
C. 3 ~h
Step-by-step solution
aligned & h = 2 ~T r g & h 1 r aligned And A = r ^2 r A h 1 A Now, h₂ h₁ = A₁ A₂ aligned & h₂ h = A A / 9 =3 & h₂=3 h aligned
