A capillary tube of radus r is immersed in water and water rises in it

1.	A capillary tube of radus r is immersed in water and water rises in it to a height h. The mass of water in the capillary tube is 5g . Another capillary tube of radius 2r is immersed in water. The mass of water that will rise in this tube is …….
Answer» `2.5g` `5.0g` 10 g 20 g Solution :`H=(2Tcostheta)/(rrhog)` MASS of water in the FIRST tube , `m=pir^(2)hrho=pir^(2)xx((2Tcostheta)/(rrhog))xxdelta` `=(2pirTcostheta)/(g)` `thereforempropttr therefore(m.)/(m)=(2r)/(r)=2` or `m.=2m=2xx5g=10g`
