Three liquids of densities ρ 1 , ρ 2 and ρ 3 (with ρ 1 > ρ 2 > ρ 3 ), having the same value of surface tension T, rise to the same height in three identical capillaries. The angles of contact θ 1 , θ 2 and θ 3 obey
A
π > θ 1 > θ 2 > θ 3 < 
B
> θ 1 > θ 2 > θ 3 
0
C
0 
θ 1 < θ 2 < θ 3 < 
θ 1 < θ 2 < θ 3 <
D
< θ 1 > θ 2 > θ 3 < π
Text Solution
Verified by ExpertsThe correct answer is:
C
h = 
cos θ 1 > cos θ 2 > cos θ 3 as ρ 1 > ρ 2 > ρ 3 0 ≤ θ 1 < θ 2 < θ 3 < π /2
