Find the thrust acting on the human body due to atmospheric pressure. Take the surface area of a man of middle size to be `1.5m^2` and atmospheric pressure (1 atm)`=1.013xx10^5` Pa.

Answer» Here, surface area of the human body, `A=1.5m^2`
pressure acting on the body, `P=1.013xx10^5Pa=1.013xx10^5(N)/(m^2)`
Thus, thrust acting on the human body, `F=PxxA=(1.013xx10^5(N)/(m^2))xx(1.5m^2)`
`=1.52xx10^5N`
`=1.52xx10^4kgwt=15.2tonwht`
