The maximum length of water column that can stay without falling in a vertically held capillary tube of diameter 1 mm and open at both the ends is
(Acceleration due to gravity \(=10 \mathrm{~ms}^{-2}\) and surface tension of water \(=0.07 \mathrm{Nm}^{-1}\) )
- A 2.8 cm
- B 5.6 cm
- C 1.4 cm
- D 0 cm
Answer & Solution
Correct Answer
(A) 2.8 cm
Step-by-step Solution
Detailed explanation
\(L = \frac{2T}{\rho r g}\) \(L = \frac{2 \times 0.07}{1000 \times (0.5 \times 10^{-3}) \times 10}\) \(L = 0.028 \text{ m}\) \(L = 2.8 \text{ cm}\)
