Question
If a capillary of radius r is dipped in water, the height of water that rises in it is h and its mass is M. If the radius of the capillary is doubled the mass of water that rises in the capillary will be : -
Options
A.4M
B.2M
C.M
D.
Solution
Mass of water M = volume × density = πr2hρ
∵ hr = constant ⇒ M ∝ r ⇒
∵ hr = constant ⇒ M ∝ r ⇒
