Question
A capillary tube of radius r is immersed in water and water rises in it to a height h. The mass of water in the capillary tube is 5 g. Another caillary tube of radius 2r i s immersed in water. The mass of water that will rise in this tube is : -
Options
A.2.5 g
B.5.0 g
C.10 g
D.20 g
Solution
Weight of rise liquid = 2πrT cosθ
mg = 2πrT cosθ ∝ m ∝ r
⇒
= 2
⇒ m2 = 2m1 = 2 × 5g = 10g.
mg = 2πrT cosθ ∝ m ∝ r
⇒
= 2⇒ m2 = 2m1 = 2 × 5g = 10g.
