when a fortins barometer is used to measure the pressure on the surface of the earth and on the top of a building the main scale reading is found to be the same and the Vernier scale reading is found to be 9 and 0, respectively. If one M.S.D. is 1mm and number of Vernier scale divisions is 10, calculate the height of the building. Take the average density of air as 1.3g/cubic centimeter, and that of mercury as 13.6 g/cubic centimeter.
