Question

When a capillary tube is dipped in a liquid, the liquid surface becomes curved due to force of adhesion (F1) and force of cohesion (F2). Choose the
correct statement
(A) Angle made by resultant force of F, and F, makes an angle tan' (

)
(B) The meniscus will be plane if F2 = V2F1
(C) F2 < V2F , the liquid surface will be concave upward
(D) F, > V2F , the liquid will be convex upward​

Answer 1

Answer:

the liquid rises to a height h in the tube. The free liquid surface inside, the tube is hemispherical in shape. The tube is now pushed down so that the height of the tube outside the liquid is less than. Then
