A capillary tube stands with its lower end dipped into liquid for which the angle of contact is 90°. The liquid will (a) neither rise nor fall. (b) get depressed only. (c) rise only. (d) rise upto the top of the tube.

Answer: (a). h = (2Tcos θ)/(rρ g) and cos 90° = 0, so h = 0. The meniscus is flat: the liquid neither rises nor falls. So the answer is (a).
