∵ g text eff =0 Then height =50 cm

Q. In a capillary tube experiment, a vertical $50 c m$ long capillary tube is dipped in water. The water rises up to a height of $20 c m$ due to capillary action. If this experiment is conducted in a freely falling elevator, the length of the water column becomes :

50 cm

20 cm

30 cm

Zero

$∵ g_{eff} = 0$
Then height $= 50 c m$
