The pressure due to atmoshere is `1.013xx10^5` Pa. Find the force exerted by the atmosphere on the top surface of a table 2-0 m long and 1-0m wide.

Explanation

Here pressure due to the atmosphere,
`P=1.013xx10^(5)Pa`
`=1.013xx10^(5)Nm^(-2)`
Area on which atmospheric pressure acts,
`A=2.0mxx1.0m=2.0m^(2)`
Thus, force exerted by the atmosphere,
`F=PA=(1.013xx10^(5)Nm^(-2))xx(2.0m^(2))`
`=2.026xx10^(5)N`
