CapillarityHardQuestion 30955
Question
A capillary tube is dipped in water at angle 60° to vertical. Capillary rise is h. Rise compared to vertical tube (h₀) is:
- Ah = h₀/cos60°Correct
- Bh = h₀
- Ch = h₀ × cos60°
- Dh = h₀ × sin60°
Correct answer
h = h₀/cos60°
Explanation
Vertical component of capillary rise = h cosθ_tilt = h₀. So h = h₀/cos60° = 2h₀. The actual column length increases but vertical height stays same.
