If the normal atmospheric pressure in a laboratory supports a column of mercury 0.76m high and the relative density of mercury is 13.8, then the height of water column which atmospheric pressure will support in the same laboratory at the same time is
0m
10m
13m
14m
18m
Correct answer is B
Density of H2O = 1gcm3
Density x pressure = constant
D1 x P1 = D2 x P2
13.6 x 0.76 = 1 x P2
P2 = 10m
