Asked by Rilwan

A uniform capillary tube closed at one end contained dry air trapped by a thread of mercury 8.5×10^-2m long.When the tube was held horizontally the length of the air column was 5×10^-2m,when it was held vertically with the closed end downwards the length was 4.5×10^-2m.Determine the value of the atmospheric pressure.g=10m/s, density of mercury 1.36×10^4kg/m^-3
