Water rises to a height of 15 ~mm in a capillary tube having cross-sectional area 'A'. If cross-sectional area of the tube is made ' A^ 3 then the water will rise to a height of
Options
- A15 3 10⁻³ ~m
- B20 3 10⁻³ ~m
- C5 3 10⁻³ ~m
- D10 3 10⁻³ ~m
Correct answer
A. 15 3 10⁻³ ~m
Step-by-step solution
h 1 r since A = r ², A r h 1 A h ₂ ~h ₁ = A ₁ ~A ₂ = 3 A ₁ ~A ₂ =3 h ₂= 3 ~h ₁= 3 15 10⁻³ ~m =15 3 10⁻³ ~m
