A glass capillary tube (closed from tap) of inner diameter `0.28mm` is lowered vertically into water in a vessel. The pressure in the capillary tube so that water level in the tube is same as that in the vessel is `N//m^(2)` is (surface tension of water `=0.7N//m` and atmospheric pressure `=10^(5)N//m^(2)`.
