Question:medium
Water rises in a capillary tube of radius $r$ up to a height $h$. The mass of water in the capillary is $m$. The mass of water that will rise in a capillary tube of radius $\frac{r}{3}$ will be
Water rises in a capillary tube of radius $r$ up to a height $h$. The mass of water in the capillary is $m$. The mass of water that will rise in a capillary tube of radius $\frac{r}{3}$ will be
Show Hint
Physics Tip : Although the water rises higher in a thinner tube ($h \times 3$), the cross-sectional area decreases significantly ($A \times 1/9$), resulting in a net decrease in the mass of the water column.
