Question

What depth of mercury creates a pressure of 100000 Pa (density of mercury is
13.6 g/cm 3 )
[Hint – depth refers to height of mercury column. Use formula P = hrhog]

Answer 1

Explanation:

ρ=13.6g/xcc=13.6×103=13600kg/m3

g=9.8m/s2

h=0.76m

So, P=Po+ρgh=105Pa+13600×9.8×0.76

                        =201292.8Pa.
