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

  • A
    $\theta_1 > \theta_2 > \theta_3$
  • B
    $\theta_1 < \theta_2 < \theta_3$
  • C
    $\theta_1 = \theta_2 = \theta_3$
  • D
    $\theta_1 > \theta_2 < \theta_3$
