Water rises to a height of 2 ~cm in a capillary tube. If crosssectional area of the tube is reduced to 1 16 ^ th of initial area, then water will rise to a height of
Options
- A4 ~cm
- B8 ~cm
- C12 ~cm
- D16 ~cm
Correct answer
B. 8 ~cm
Step-by-step solution
aligned & h = 2 ~T r g & h ₂ ~h ₁ = r ₁ r ₂ & Area A = r ^2 A r ^2 & A ₁ ~A ₂ = r ₁^2 r ₂^2 or r ₁ r ₂ = A ₁ ~A ₂ = 16 & r ₁ r ₂ =4 & h ₂ ~h ₁ =4 or h ₂=4 ~h ₁=4 2=8 ~cm aligned
