AP EAPCET 2024 - 19th May Evening Shift | Fluid Mechanics Question 20 | Physics

If $S_1, S_2$ and $S_3$ are the tensions at liquid-air, solid-air and solid-liquid interfaces respectively and $\theta$ is the angle of contact at the solid-liquid interface, then

$S_1 \cos \theta+S_2 \sin \theta=S_3$

$S_1 \cos \theta+S_3=S_2$

$S_2 \cos \theta+S_3=S_1$

$S_3 \cos \theta+S_1=S_2$
