Angle of Contact & Capillarity question from MHT CET 2025 (19 Apr, Shift 1)

Q19MHT CET 2025 · 19 APR · SHIFT 1Easy

Angle of Contact & Capillarity

A liquid rises to a height of 2.4 cm in a glass capillary P. Another glass capillary Q having diameter $80\%$ of capillary $P$ is immersed in the same liquid. The rise of liquid in capillary $Q$ is

Show answer and solution

Answer: (c)

$h \propto \frac{1}{d}$ for the same liquid.
$h_Q = h_P \cdot \frac{d_P}{d_Q} = \frac{2.4}{0.8} = 3\text{ cm}$
So the answer is (c) $3$ cm.
