Question

the pressure due to the atmosphere is 1.01*10³ Pa. find the force exerted by the atmosphere on the top surface of the table 2.0 m long and 1.0m wide.

Answer 1

Surface area of table=length*breadth

So,area of table=2m*1m

So,area of table=2m^2

Pressure=Force/Area

So,Force=Pressure*Area

So,Force=1.01*1000*2

So,Force=2020 N
