When a capillary tube of diameter 0.8 mm is dipped in a liquid having density

800\,\,kg\,\,{m^{ - 3}}

, then the height of liquid in the capillary tube rises to 4 cm. The surface tension of liquid is

\left( {\mathrm{g} = 9.8\mathrm{m}/{\mathrm{s}^2}} \right)

View answer and explanation

Correct option: C

6.3 \times {10^{ - 2}}N{m^{ - 1}}

Option C (

6.3 \times {10^{ - 2}}N{m^{ - 1}}

) is correct because it is calculated using the formula for surface tension based on capillary rise.
