A long cylinderical glass vessel has a small hole of radius r at its bottom. The depth to which the vessel can be lowered vertically in a deep water (surface tension S) without any water entering inside is

A

`T/(rhorg)`

B

`(2T)/(rho rg)`

C

`(3T)/(rho rg)`

D

`(4T)/(rho rg)`

Text Solution

Verified by Experts

The correct Answer is:
B
Pressure due to liquid column
= Pressure difference due to S.T
` h rho g = (2T)/R " " :. h = (2T)/(r rhog)`
