A glass capillary tube of inner diameter 0.28 mm is lowered vertically 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 the vessel in `(N)/(m^(2))` is (surface tension of water `=0.07(N)/(m)` atmospheric pressure `=10^(5)(N)/(m^(2))`A. `10^(3)`B. `99xx10^(3)`C. `100xx10^(3)`D. `101xx10^(3)` |
