A capillary tube of radius 'r' is immersed in water and water rises to a height of 'h'. Mass of water in the capillary tube is `5 xx 10^ -3 kg`. The same capillary tube is now immersed in a liquid whose surface tension is sqrt2 times the surface tension of water. The angle of contact between the capillarv tube and this liauid is `45^@`. The mass of liquid which rises into the capillary tube now is (in kg)

Options

A. `5 xx 10^(-3)`
B. `2.5 xx 10^(-3)`
C. `5 sqrt (2) xx 10^(-3)`
D. `3.5 xx 10^(-3)`

Answer

A
