                If capillary tube dipped in water the water will raise in the tube so there is a concave shape formed when water raised. If it is dipped in mercury then hg falls due to cohesive forces then there is a convex shape formed.

                Capillary rise will happen because the adhesive force is greater than cohesive force hence angle <90 hence concave is right.

                Concave is the right answer. I agree with the given option.

                Cancave is the right answer due to capillary action.

                Convex is for mercury (hg) for water it is concave.

                Convex is the correct answer.

                Convex is the right answer.

                Cancave is right for water.

                Due to capillary fall.
