Question

ii)if the surface of a liquid is plane, then the angle of contact of the liquid with the
walls of the container is -
a) Acute angle
b) obtuse angle
c) 90°
d) 09​

Answer 1

Answer:

The angle of contact with wall of container is angle b/w liquid surface & normal to the wall of container. Hence for a plane liquid angle of contact is 0 degree ans d

Answer 2

Answer:

90 degree because

Explanation:

because the angle between the plane surface and the boundary of contact of the liquid makes an right angle so that the answer is (c) .
