Angle of Contact & Capillarity question from MHT CET 2025 (25 Apr, Shift 1)

Q18MHT CET 2025 · 25 APR · SHIFT 1Easy

Angle of Contact & Capillarity

In a capillary tube of area of cross-section 'a' water rises to height ' $h$ '. To what height will water rise in a capillary tube of area of cross-section $4a$ ?

Show answer and solution

Answer: (c)

$h \propto \frac{1}{r}$ , $A = \pi r^2$ . Area $4a \Rightarrow$ radius doubles.
$h' = \frac{h}{2}$
So the answer is (c) $\frac{h}{2}$ .
