Question

The pressure difference between two floor of a building is 30000 pascal find the vertical distance between the floor density of water =10³kg/m³ g = 10 m/s³​

Answer 1

Answer:

Correct option is

A

9 m

Difference in pressure of water at ground floor and third floor

=(120000−300000)=900000Pa

Density of water =1000kgm

−3

Let 'h' be the height third floor.

P=hdg

h=

dg

p

=

1000×10

90000

=9m.
