If a liquid wets a surface,is its angle of contact acute or obtuse?

$A$ liquid is filled in a spherical container of radius $R$ up to a height $h$. At this position,the liquid surface at the edges is horizontal. The contact angle is:

Explain the angle of contact in the context of intermolecular forces.

What is the nature of the meniscus for a liquid with an angle of contact of $0^{\circ}$?

$A$ capillary tube is dipped vertically in a liquid. If the liquid surface is hemispherical,then the angle of contact $\theta$ is

$A$ liquid does not wet the solid surface if the angle of contact is
