Question
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 : -
Options
A.10 cm
B.20 cm
C.30 cm
D.Zero
Solution
geff = 0, h = 
so water rises maximum height i.e. length of the capillary = 30 cm
so water rises maximum height i.e. length of the capillary = 30 cm
