A capillary tube of radius r is immersed in water and water rises in it to a height h. The mass of the water in the capillary is 5 g. Another capillary tube of radius 2r is immersed in water. The mass of water that will rise in this tube is:
  1. 5.0 g
  2. 10.0 g
  3. 20.0 g
  4. 2.5 g

Solution

The relation between mass and radius of the capillary tube is given by,mr

m2m1=r2r1

m25=2rr

m2=10 g
