MCQ
A mercury column of height 76 cm stands in a barometer. Taking density of mercury 13,600 kg/m^3 and g = 10 N/kg, the pressure exerted is:
Unit-5 Pressure and Deformation in Solids
A 103,360 Pa
B 10,336 Pa
C 1,033,600 Pa
D 103.36 Pa
Explanation

P = h rho g = 0.76 x 13,600 x 10 = 103,360 Pa, close to standard atmospheric pressure.
