A capillary of `1mm` diameter, is dipped vertically in a `rho` ot of water. If gauge pressure of the water. If gauge pressure of the water in the tube `5.0 cm` below the surface is `2lambda N//m^(2)` then find `lambda`. Surface tension of water `= 0.075 N//m`. (take `g = 9.8 m//s^(2)` & `rho_(w) = 1000 kg//m^(3)`)
