An airplane window has an area of 825`cm^2`. Cabin pressure is 1 atm, and the outside pressure in 0.3 atm. Find the force produced by air pressure on the window.

Text Solution

Verified by Experts

`F=P_1A-P_2A`
`=(P_1-P_2)A`
`A=(1atm-0.3atm)(825cm^2)`
`=(0.7)(1.01xx10^5(n)/(m^2))(825xx10^-4m^2)=5.83xx10^2N`
