5. A Fortin's barometer has a main scale and a vernier
scale to measure the atmospheric pressure. The main
scale graduations are in mm. If 49 main scale divi-
sions coincide with 50 vernier divisions, find the
least count of the instrument, in Pa. (Given pressure
exerted by 76 cm column of mercury = 10^5 Pa)​
