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

$A$ 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:

The meniscus of mercury in the capillary tube is

Consider a spherical body,one third of its volume is filled with a liquid which has a contact angle of zero with the surface of the sphere. If this sphere (along with the liquid) is taken to gravity-free space,then the shape of the liquid inside the sphere will look like:

Give reason: The wing of a duck does not get wet in water.
