Angle of Contact & Capillarity

When a capillary tube of radius 'r' is immersed in water, rise of water is upto height 'h'. The mass of water in capillary tube is 'm'. When another capillary tube of radius 'xr' is immersed in water, the mass of water that will rise in this tube is

Show answer and solution

Answer: (a)

$m = \pi r^2 h\rho$ and $h \propto \frac{1}{r}$ , so $m \propto r$ (also $mg = 2\pi rT$ ).
Radius $xr \Rightarrow$ mass $= x\,m$ .
So the answer is (a) $x \cdot m$ .
