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 2 r is immersed in water. The mass of water that will rise in this tube is:

Options

  1. A5.0 g
  2. B10.0 g
  3. C20.0 g
  4. D2.5 g

Correct answer

B. 10.0 g

Step-by-step solution

The relation between mass and radius of the capillary tube is given by, m ∝ r ⇒ m 2 m 1 = r 2 r 1 ⇒ m 2 5 = 2 r r ⇒ m 2 = 10   g
