Answer:
Net forces which pushes the window is 30342.78 N.
Explanation:
Given:
Dimension of the office window.
Length of the window = m
Width of the window = m
Area of the window =
Difference in air pressure = Inside pressure - Outside pressure
= atm =
atm
Conversion of the pressure in its SI unit.
⇒ atm =
Pa
⇒ atm =
Pa
We have to find the net force.
We know,
⇒ Pressure = Force/Area
⇒
⇒
⇒ Plugging the values.
⇒
⇒ Newton (N)
So,
The net forces which pushes the window is 30342.78 N.
