MHT CET 2026 13th April Morning Shift | Fluid Mechanics Question 40 | Physics

Three liquids have same surface tension and have densities $\rho_1, \rho_2$ and $\rho_3$ $(\rho_1 > \rho_2 > \rho_3)$. In three identical capillaries rise of liquid is same. The corresponding angles of contact $\theta_1, \theta_2$ and $\theta_3$ are related as

$\theta_1 > \theta_2 > \theta_3$

$\theta_1 < \theta_2 < \theta_3$

$\theta_1 = \theta_2 = \theta_3$

$\theta_1 > \theta_2 < \theta_3$
