The height of a mercury barometer is 75 cm at sea level and 50 cm at the top of a hill. Ration of density of mercury to that of air is 10^(4) . The height of the hill is

the height of a mercury barometer is 76 cm at sea level and 50 cm at the top of a hill. Determine the height of the hill. (Densities of air and mercury are 1.36 kg m^(-3) and 13.6 xx 10^(3) kg m^(-3)) hint : Difference of pressure =76 cm - 50 cm = 26 cm of mercury 0.26 xx 9.8 xx 13.6 xx 10^(3) Nm^(-2) pressure due to h metre of air = h xx 9.8 xx 1.36 ]
