Question

Consider the shape (x) of the
water-air interface near a plane
wall. Take the curvature as R−1 
d
2/dx
2
. Consider the pressure
difference across the interface to
be p = g. The surface tension
is . At x = 0, the area-wetted
contact angle is , while as x→,
 = 0. Find the maximum height
h at the wall.
