Question 33 of 249

Three liquids of densities $ρ_{1}, ρ_{2} a n d ρ_{3}$ (with $p_{1} > p_{2} > p_{3}$ ), having the same value of surface tension T, rise to the same height in three identical capillaries. The angles of contact $θ_{1}, θ_{2} a n d θ_{3}$ obey

(a) $\frac{π}{2} > θ_{1} > θ_{2} > θ_{3} \geq 0$

(b) $0 \leq θ_{1} < θ_{2} < θ_{3} < \frac{π}{2}$

(c) $\frac{π}{2} < θ_{1} < θ_{2} < θ_{3} < π$

(d) $π > θ_{1} > θ_{2} > θ_{3} > \frac{π}{2}$
