Water rises to height 2 2 ~cm in glass capillary tube. The height to which same water rises in another capillary having 1 4 area of cross-section is

Options

  1. A16 4 ~cm
  2. B4 4 ~cm
  3. C8 4 ~cm
  4. D2 2 ~cm

Correct answer

B. 4 4 ~cm

Step-by-step solution

h ₁=2.2 ~cm , ~h ₂=? ~h ₁ r ₁= h ₂ r ₂ ~h ₁ A ₁ = h ₂ A ₂ ~h ₂= h ₁ A ₁ A ₂ =2.2 2=4.4 ~cm
