If atmospheric pressure is 1.01*10^5 Pa,how much pressure will the air exert on a window of area 100*50 cm.

What do you think? We need you to show so,e effort and outline where you are struggling before help can be given.

I think we must have the weight of air and then we can find it.but how? I don't know it. Please help.

Normally the question would have you looking for Force...

 

1N/1m^2 = 1Pa

1N/1m^2 = 1Pa

 

The point about force might be a good one, Endy.

However such calculation does rather assume there is a perfect vacuum on one side of the window.

 

The question needs clarification to answer properly.

The same pressure as on the other side of the window.

No, the question is fine. If it's vacuum or atmosphere, it has no effect on the pressure on the side in question.

The same pressure as on the other side of the window.

 

I have several vacuum systems that beg to differ with you.

Yeah, does look like it was simply misworded:

I think the question reads better using psi(pounds-force per square inch). Just my own musings though.

At home too. Thankfully the difference tends to be small and the equalization fast.

If the question is read carefully, it will be found that the question demands the PRESSURE exerted by air , given that the atmospheric PRESSURE is 1.013*10^5 Pa.
