Water rises in a capillary tube of radius ' r ' up to height ' h '. The mass of water in capillary is ' m '. The mass of water that will rise in capillary of radius r / 3 will be

Step-by-step solution

Rise of water in capillary tube is given by h = 2 ~T rgg For water, =1 Also, the radius of capillary tube becomes (r/3). h ^ = 3 2 ~T r ~g ~h ^ =3 ~h Now, m= r^2 ~h m ^ = ( r / 3)^2(3 ~h ) = r ^2 ~h 3 = m 3
