Three liquids have same surface tension and densities ₁, ₂ , and ₃ ( ₁> ₂> ₃ ) . In three identical capillaries rise of liquid is same. The corresponding angles of contact ₁, ₂ and ₃ are related as
Options
- A₁> ₂> ₃
- B₁> ₃> ₂
- C₁ < ₂ < ₃
- D₁= ₂= ₃
Correct answer
C. ₁ < ₂ < ₃
Step-by-step solution
Rise in capillary tube, h = 2 ~T rpg Given that, h , T , r and g are constant. array ll & = constant & i.e., ₁ ₁ = ₂ ₂ = ₃ ₃ & as ₁> ₂> ₃ & ₁> ₂> ₃ & ₁ < ₂ < ₃ array
