Identify the correct figure which shows the relation between the height of water column in a capillary tube and the capillary radius.
- A (ii)
- B (iv)
- C (i)
- D (iii)
Answer & Solution
Correct Answer
(A) (ii)
Step-by-step Solution
Detailed explanation
Height if liquid in capillary tube is given by,
\(\begin{aligned}
& h=\frac{2 T \cos \theta}{r \rho g} \\
\therefore \quad & h \propto \frac{1}{r}
\end{aligned}\)
This is correctly depicted by graph (ii).
\(\begin{aligned}
& h=\frac{2 T \cos \theta}{r \rho g} \\
\therefore \quad & h \propto \frac{1}{r}
\end{aligned}\)
This is correctly depicted by graph (ii).
