# A capillary tube of radius 'r' is immersed in water and water rises in it to a height 'h'. Mass of water in the capillary tube is $5 \times 10^{-3}kg$ . Another capillary tube of radius $\bigg( \large\frac{r}{2} \bigg)$ is immersed in water. The mass of water that will rise in this tube is

$\begin {array} {1 1} (1)\;7.5 \times 10^{-3}kg & \quad (2)\;1 \times 10^{-3}kg \\ (3)\;2.5 \times 10^{-3}kg & \quad (4)\;5 \times 10^{-3}kg \end {array}$

Can you answer this question?
