Question

Surface tension of two liquids (having same densities), $T_1$ and $T_2$ are measured using capillary rise method utilizing two tubes with inner radii of $r_1$ and $r_2$ where $r_1 > r_2$ . The measured liquid heights in these tubes are $h_1$ and $h_2$ respectively. [Ignore the weight of the liquid about the lowest point of meniscus]. The heights $h_1$ and $h_2$ and surface tensions $T_1$ and $T_2$ satisfy the relation :

A
$h_1 > h_2$ and $T_1 < T_2$
B
$h_1 = h_2$ and $T_1 = T_2$
C
$h_1 < h_2$ and $T_1 = T_2$
D
$h_1 > h_2$ and $T_1 = T_2$

Accepted Answer

C. $$h_1 < h_2$$ and $$T_1 = T_2$$

Answer
