When one end  of the capillary  is dipped  in water, the height  of water  column  is `'h'`. 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 is  (Surface  tension of water  `= 7 xx 10^(-2) N//m`)
