The angle of contact between a solid and a liquid is a characteristic property of

The angle of contact between a solid and a liquid is a characteristic property of

Liquid rises to a height of 2 cm in a capillary tube and the angle of contact between the solid and the liquid is zero. If the tube is depressed more now so that top of capillary is only 1 cm above the liquid, then the apparent angle of contact between the solid and the liquid is
