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 te water column becomes

A

10 cm

B

20 cm

C

30 cm

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
C
As `g_("effective") = 0`
