Angle of Contact & Capillarity question from MHT CET 2024 (4 May, Shift 2)

Q31MHT CET 2024 · 4 MAY · SHIFT 2Easy

Angle of Contact & Capillarity

Identify the correct figure which shows the relation between the height of water column in a capillary tube and the capillary radius.

Show answer and solution

Answer: (b)

$h = \frac{2T\cos\theta}{r\rho g} \Rightarrow hr$ = constant.
The $h$ vs $r$ graph is a rectangular hyperbola, which is figure (B).
Figure (B) is option (a).
