A glass capillary tube of inner diameter `0.28 mm` is lowered verically into water in a vessel. The pressure to be applied on the water in the capillary tube so that water level in the tube is same as that in the vessel is `lambda xx 10^(5) N//m^(2)`. Then find `lambda` in nearest integer (surface tension of water `= 0.07 N//m` and atmospheric pressure `= 10^(5)N//m^(2)`) :
