By inserting a capillary tube upto a depth $l$ in water, the water rises to a height$h$. If the lower end of the capillary tube is closed inside water and the capillary is taken out and closed end opened, to what height the water will remain in the tube, when $l h$?

(c) Due to surface tension water rises in the capillary tube upto a height $h$ with concave meniscus on both the sides. Therefore, the total height of water column in the capillary tube $= h + h = 2h$
