A capillary tube of radius

r

can support a liquid of weight

6.28 \times 10^{-4} \mathrm{~N}

. If the surface tension of the liquid is

2 \times 10^{-2} \mathrm{~N} / \mathrm{m}

then find:

(1) Radius of capillary tube.

(2) Internal circumference of capillary tube.

View answer and explanation

Correct option: C

5 , 31.4

Option C (

5 , 31.4

) is correct because the radius is calculated using the formula relating surface tension, radius, and weight, and the circumference is then calculated from the radius.
