alleryCapillary rise h for liquid in tube of radius r:
Ah = r
Bh = γ/r
Ch = ρgh
Dh = 2γ cos θ / (ρ g r)
Answer & Solution
Correct answer: D. h = 2γ cos θ / (ρ g r)
**Jurin's law:** h = 2γ cos θ / (ρ g r). θ = contact angle.
**Water in glass:** θ ≈ 0, rises.
**Mercury in glass:** θ ≈ 140°, depresses.
**Inverse relation:** thinner tube, higher rise.
