In a capillary tube experiment, a vertical, 30 cm long capillary tube is dipped in water. The water rises up to a height of 10 cm due to capillary action. If this experiment is conducted in a freely falling elevator, the length of the water column becomes ___________ Correct Answer 30 cm

In the freely falling elevator, g = 0. Water will rise (h=2σcosθ/rρg) to fill the entire 30 cm length of the tube.
