    33
    One end of a capillary tube is dipped in water; the rise of water column is ' hh '. The upward force of 98 dyne due to surface tension is balanced by the force due to the weight of the water column. The inner circumference of the capillary is (surface tension of water =7×10−2Nm−1= 7 \times10^{- 2}Nm^{- 1})

    When one end of a capillary tube is dipped in water, the height of water column is ' hh '. The upward force of 105 dyne due to surface tension is balanced by the force due to the weight of water column. The inner circumference of the capillary tube is (Surface tension of water =7×10−2 N/m= 7 \times10^{- 2}\text{ }N/m )

    When one end of the capillary is dipped in water, the height of water column is ' hh '. The upward force of 108 dyne due to surface tension is balanced by the force due to the weight of water column. The inner circumference of the capillary is (surface tension of water =7.2×10−2 N/m= 7.2 \times10^{- 2}\text{ }N/m )
