Properties Of Solids And Liquids Question 187

Question: If water rises in a capillary tube upto 3 cm. What is the diameter of capillary tube (Surface tension of water $= 7.2 \times 10^{2} N / m$ ) [RPMT 2002]

Options:

A) $9.6 \times 10^{4} m$

B) $9.6 \times 10^{3} m$

C) $9.6 \times 10^{2} m$

D) $9.6 \times 10^{1} m$

Show Answer

Answer:

Correct Answer: A

Solution:

$h = \frac{2 T \cos θ}{r d g}$ , for water $θ = 0^{\circ}$

therefore $r = \frac{2 T}{h d g} = \frac{2 \times 7.2 \times 10^{- 2}}{3 \times 10^{- 2} \times 10^{3} \times 10} = 4.8 \times 10^{- 4}$ \ $d = 2 r = 9.6 \times 10^{- 4} m$
